TL;DR: RK3588 Custom Core Board and Carrier Board
SHENZHEN, China, September 12, 2026 - Wanlin Manufacturing Group pushed lot 187 of the WF-C3588-I1 board out of the Longgang plant this week, 6,450 units for Osaka, Japan, with the export declaration naming Longgang as the place of origin.
AndroidSBC site report from running WF-C3588 custom motherboard installations serving Osaka, Japan. AndroidSBC is opening the full WF-C3588 custom motherboard programme to Japan: nine variants on the Rockchip RK3588 platform with 6 TOPS NPU, 8K H.265 decode, dual Gigabit Ethernet and up to 32GB of LPDDR5. Every variant ships from the Wanlin Longgang facility with OEM branding available, ODM carrier design handled in-house, and per-lot CE, FCC, UKCA, RoHS and IEC 62368-1 documentation.

About AndroidSBC and the Rockchip RK3588 Board Family
Wanlin Manufacturing Group has been building custom Android and Linux boards in Shenzhen since 2013, and AndroidSBC is the group's export-facing brand. The WF-C3588 is the current custom motherboard programme: nine variants on the same Rockchip RK3588 octa-core 8nm silicon with 6 TOPS NPU, 8K H.265 decode, dual Gigabit Ethernet and up to 32GB of LPDDR5. Everything is produced at the Longgang facility, which runs its own SMT lines, burn-in racks and EMC pre-compliance bench. Osaka and Japan buyers typically come to the WF-C3588 for one of three reasons: nine custom categories on one silicon, a source factory that takes OEM and ODM work seriously, or a supplier that carries the certification paperwork instead of leaving it to the importer.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-I1 (Custom Industrial Motherboard for Fanless and Wide-Temperature Control) holds its display output and its decoder load at the same time through the burn-in loop, a combination that the legacy boards in the comparison column cannot sustain. For Japan importers sourcing the WF-Series, the 8GB + 32GB (WF-C3588-I1-B) variant is the typical configuration for the custom industrial control and HMI programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.
Challenges in Sourcing Custom Industrial Motherboard for Fanless and Wide-Temperature Control for Japan Buyers
The first thing Japan procurement teams learn about the custom industrial motherboard for fanless and wide-temperature control category is that quotation speed and delivery reliability are inversely related. The Rockchip RK3588 needs a wafer slot that a broker cannot create, so the fastest quotes are often the ones attached to the least secure allocation. Then there is the software build. A board that boots is not the same as a board that carries the certified stack a Japan retailer will accept, and the gap is normally found during inbound QC rather than at the factory gate.
Then there is the certification file. A stamp is cheap; a Technical File with notified-body reports dated inside twelve months is not, and the difference only matters when a Japan customs officer asks for it. AndroidSBC closes the loop at the source factory: custom configuration assembled, certified image burned, burn-in barcode attached per unit, Technical File issued with the lot. The nine WF-C3588 variants cover industrial HMIs, panel PCs, PLC upgrades, SCADA nodes, DIN-rail controllers, factory automation, data acquisition, IIoT gateways, and machine control and each ships in three memory configurations, so most Osaka requirements can be met from standard stock rather than a from-scratch run.
For Japan specifically, the file travels with the goods. In Japan PSE under the DENAN law and the MIC Giteki mark are both required, and the certification is normally held by the Japanese importer. AndroidSBC prepares the PSE under the DENAN law with the MIC Giteki mark documentation for METI / MIC, attaches the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), and consigns the lot to Port of Yokohama on the Yokohama to Shanghai lane.
Competitive Comparison: WF-C3588-I1 vs Competing RK3588 Boards
Three families of board chase the same custom industrial motherboard for fanless and wide-temperature control socket. The first is catalogue hardware with fixed memory and fixed I/O, the second is re-badged stock where nobody owns the schematic, and the third is a real custom platform built by the factory that runs the SMT line. The WF-C3588-I1 belongs to the third family and separates itself on Rockchip RK3588, on customization depth from schematic to firmware, and on a certified image burned per lot.
- vs commercial boards in industrial dress: the WF-C3588-I1 is designed to -40C to 85C from the schematic up, not a consumer board with a bigger heatsink.
- vs local integrator bundles: the carrier design, the BSP port and the DIN-rail chassis all come from one Longgang engineering desk, so responsibility never splits across vendors.
- vs legacy PLC upgrade paths: the 6 TOPS NPU adds on-device vision and predictive maintenance to a PLC retrofit without a separate AI box.
- vs trading-company boards: the per-lot Technical File, the aging record and the EMC pre-compliance bench all live inside the source factory.
Global Custom Industrial Motherboard and Panel PC Market Trends
Buyers in Osaka are reading the Custom Industrial Motherboard and Panel PC curve before they commit to a custom industrial motherboard for fanless and wide-temperature control programme. MarketsandMarkets reports the Edge AI hardware segment at USD 26.9 billion in 2025 with a 32.7 percent CAGR to USD 108.2 billion by 2030 (MarketsandMarkets, 2025-2030), used here as the RK3588-class silicon baseline rather than as a number for this category. That baseline breaks into three practical demand patterns for the WF-C3588 in Japan:
- Industrial HMI panel: a machine builder replaces an aging Windows panel with a fanless HMI running a Yocto image and a custom UI.
- Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-I1 board carries that headroom without a board change.
- SCADA edge node: a utility deploys DIN-rail controllers that aggregate substation data and push it over dual Gigabit links.
The Custom Industrial Motherboard and Panel PC commentary has shifted from unit growth to supply reliability, and that shift favours suppliers who control their own SMT and burn-in lines.
The common thread in Japan is that single orders are being replaced by blanket agreements with a monthly release, because a custom board programme that has to survive a twelve-month window cannot absorb an allocation gap in the middle of it.
Partner Success Story: Trident Vending in Osaka, Japan
Trident Vending, a smart vending operator serving the Japan market, deployed 5,400 custom WF-C3588-K4 vending machine boards for an unattended retail estate. The rollout covered the industrial hmi panel, scada edge node, and factory automation cell workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.
- Deployed: 5,400 custom WF-C3588-K4 vending machine boards for an unattended retail estate
- Region: Osaka, Japan
- Models used: WF-C3588-I1 (lead SKU), plus eight sibling custom RK3588 board variants in the same platform family
- Certifications handled: CE, FCC, UKCA, RoHS, REACH, IEC 62368-1, EN 55032, EN 55035, plus optional UL 60950-1, GMS, Widevine L1 and Dolby Audio per variant
- Logistics: FOB Yantian with the Wanlin Group Longgang source factory named on the export declaration, entering Port of Yokohama via the Yokohama to Shanghai lane
"The shelf-camera stock check on the NPU cut our route visits by a third, and the multi-serial profile drives the coin and note units without adapter boxes. When a board does fail, the burn-in barcode gets us a root-cause note with the replacement."
- Marco Bellini, IT Infrastructure Lead
Field Report: a school district rollout in Osaka, where 6,450 units of the WF-C3588-I1 board are being installed in classroom device carts
Reporter Lu Kang, on the ground in Osaka, Japan. The district took delivery of the order and dispatched installation crews to eight sites. Each WF-C3588-I1 unit was sealed into a ruggedised chassis running a managed Android image with the education services stack pre-provisioned for the district tenant, and the fleet enrolled against the MDM the same week.
The QA lead noted that the WF-C3588-I1 lot was the third consecutive run to clear the aging bench without a retest.
The inspection confirmed three things on the spot: the WF-C3588-I1 units hold the burn-in with a yield above 99.27 percent, the loaded firmware image survives a 72-hour continuous loop without credential drift, and the pallets carry the matching certification file for the destination market, covering PSE under the DENAN law with the MIC Giteki mark administered by METI / MIC, cleared for entry at Port of Yokohama on the Yokohama to Shanghai lane. Wanlin remains one of the few source factories currently shipping a nine-variant custom RK3588 motherboard line with a per-lot paper trail that Japan importers can hand straight to their customs broker.

WF-C3588-I1 Application Scenarios
The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-I1 (Custom Industrial Motherboard for Fanless and Wide-Temperature Control) as the lead SKU for Osaka and Japan programmes:
- Industrial HMI panel: a machine builder replaces an aging Windows panel with a fanless HMI running a Yocto image and a custom UI.
- PLC upgrade retrofit: a plant keeps the field wiring and swaps the controller for a CAN-equipped board with Modbus passthrough.
- SCADA edge node: a utility deploys DIN-rail controllers that aggregate substation data and push it over dual Gigabit links.
- Machine vision inspection: the 6 TOPS NPU runs defect classification at line speed on a 3.5-inch SBC inside the cabinet.
- Data acquisition gateway: a multi-serial variant logs sensor traffic from RS485 chains and buffers it during link loss.
- Factory automation cell: a systems integrator drives a robot cell and its safety stack from one wide-temperature board.
- Outdoor kiosk controller: an unattended terminal survives summer heat in a sealed enclosure with no fan to clog.
- Predictive maintenance: vibration and acoustic models run locally on the NPU and alarm before the PLC does.
Partnership Models for Osaka Buyers
The WF-C3588 custom line is available to Japan partners through three routes, and they can be mixed inside one agreement:
- OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom boot animation, custom SKU label, and a private-label certification file.
- ODM (your spec on our reference design): schematic and stack-up review, carrier or motherboard redesign, custom firmware features, and a BSP port handled by the Longgang engineering desk.
- Distribution (your channel, our stock): regional distributor rights, channel rebate, stock holding at the factory, and a framework agreement with a monthly lot release.
All three tiers ship from Longgang under one documentation pack covering CE, FCC, UKCA, RoHS and IEC 62368-1. A Osaka first order on the WF-C3588-I1 is normally the 8GB + 32GB (WF-C3588-I1-B) configuration at MOQ 5,000 units per shipment, standard samples in 1-3 days and 15-30 days to production.
Frequently Asked Questions
What exactly can be customised on an RK3588 motherboard from AndroidSBC?
Answer: Everything from the copper up. Custom PCB and PCBA, custom I/O routing, custom memory and storage configuration, custom display and camera interfaces, custom thermal profile from commercial to -40C to 85C industrial, and custom branding including silk-printed logo, packaging, SKU label and boot animation. The firmware side covers custom Android (GMS or AOSP), Ubuntu, Debian, Yocto and OpenHarmony builds with BSP ports handled by the Longgang engineering desk rather than handed to the buyer as an unmodified vendor drop.
Can AndroidSBC port a custom Android ROM or a custom Linux BSP to our carrier board?
Answer: Yes, and that work stays in-house. The ODM tier covers custom Android ROM builds with proprietary services and launchers, AOSP builds without Google services, and Linux images on Ubuntu, Debian, Yocto or Buildroot. BSP ports for custom carrier boards are executed by the Longgang engineering desk, with SDK and BSP source released to the partner under NDA. The same desk handles driver development for the I/O you added, which is the part that usually stalls when a factory forwards a vendor drop and walks away.
Can the 6 TOPS NPU on a custom board run our own AI models?
Answer: Yes. Custom NPU development covers RKNN model deployment, quantization from the major frameworks, multi-model pipelines on the triple-core NPU, and custom AI algorithm integration. The desk validates throughput on your exact memory configuration, and the deployment lands as a versioned RKNN file that OTA can update in the field, which is how Japan partners iterate models without replacing hardware.
What are the MOQ and lead times for a custom RK3588 motherboard?
Answer: Samples of standard variants leave the factory in 1-3 days. Custom builds run 15-30 days to mass production once the design is signed off, with the schematic review and carrier design handled in the same window. MOQ sits at 5,000 units per shipment on standard configurations, custom runs are quoted against volume, and small pilot batches are accepted for first-article programmes.
What certifications does a custom board need for Japan, and who handles them?
Answer: Certification is part of the customization scope, not an afterthought. The in-house file covers CE, FCC Part 15, UKCA, RoHS 2.0, REACH and IEC 62368-1 with test reports dated inside twelve months, plus GMS and EDLA tracks for custom Android and display products. The file is built for the exact configuration you ship, which matters for a custom board because a test report on a different memory fit is not a valid report at all.
How long will AndroidSBC keep supplying a custom board?
Answer: Seven years minimum, written into the framework agreement. The RK3588 platform carries a long industrial lifecycle, and Wanlin commits to the supply window, to security patches across the Android, Ubuntu LTS, Debian LTS and Yocto tracks, and to OTA update infrastructure for field-deployed units. For a custom board that is the whole point of going to a source factory: the product lifecycle is a contract term, not a hope.
Can AndroidSBC ship custom boards to Amazon FBA warehouses or 3PL consolidation points?
Answer: That is routine. AndroidSBC delivers DDP into Amazon FBA in the US, EU and Japan and into 3PL consolidation points at Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Carton and pallet configuration follows FBA inbound rules, and the place of origin on the declaration is the Wanlin Longgang source factory.
How does AndroidSBC handle RMA or DOA replacements on custom boards?
Answer: The DOA target is 0.3 percent over twelve months. For RMA, partners send the WF-C3588-I1 unit back to Longgang with the burn-in barcode attached, and replacements go out within ten business days. The per-unit record means the failure report usually carries a root cause alongside the replacement, which is what a Japan integrator running a custom configuration actually needs.
