LONGGANG, Shenzhen, September 12, 2026 - A 19,645-unit WF-C3588-E7 order for Bern, Switzerland completed burn-in and documentation at the Wanlin Longgang plant this week, the 251st lot released on the Rockchip RK3588 line.
AndroidSBC opens the custom RK3588 motherboard platform to overseas OEM buyers and industrial integrators serving Bern, Switzerland. The WF-C3588 line is a custom motherboard programme built on the Rockchip RK3588 octa-core platform (4x Cortex-A76 at 2.4GHz plus 4x Cortex-A55 at 1.8GHz on 8nm) with a triple-core NPU delivering 6 TOPS of INT8 inference, 8K H.265 decode and up to 32GB of LPDDR4X or LPDDR5. AndroidSBC, the export arm of Wanlin Manufacturing Group, builds nine custom variants at the Longgang source factory in Shenzhen for Bern and Switzerland buyers: WF-C3588-A0 custom Android motherboards, WF-C3588-I1 custom industrial boards, WF-C3588-M2 core boards and SOMs with carrier design, WF-C3588-S3 custom signage and video wall boards, WF-C3588-K4 custom kiosk and POS boards, WF-C3588-R5 custom robotics controllers, WF-C3588-N6 custom NVR boards, WF-C3588-E7 custom edge AI boards, and WF-C3588-P8 custom ARM PC and NAS boards.

About AndroidSBC and the Rockchip RK3588 Board Family
The WF-C3588 is a nine-variant custom motherboard programme from AndroidSBC, the export arm of Wanlin Manufacturing Group in Shenzhen. One Rockchip RK3588 silicon, nine custom categories: custom Android motherboards, custom industrial boards, core board and SOM work, custom signage and video wall boards, custom kiosk and POS boards, custom robotics controllers, custom NVR boards, custom edge AI boards, and custom ARM PC and NAS boards. Wanlin's Longgang plant handles SMT, burn-in and pre-shipment inspection in one building, and the export desk handles the CE, FCC, UKCA, RoHS and IEC 62368-1 file per lot. For Switzerland importers, the line covers the custom board categories a Bern distributor is most often asked to quote.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-E7 (Custom Edge AI Computing Board) 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 Switzerland importers sourcing the WF-Series, the 16GB + 64GB (WF-C3588-E7-C) variant is the typical configuration for the custom edge AI computing programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.
Challenges in Sourcing Custom Edge AI Computing Board for Switzerland Buyers
The recurring problem for Bern and Switzerland buyers sourcing a custom edge ai computing board is not the headline unit price, it is whether the allocation actually holds. The Rockchip RK3588 needs its own wafer slot, and brokers who quote from stock frequently cannot honour that slot once a 19,645-unit push lands mid-quarter. The software question follows immediately. The hardware spec sheet is easy to verify; the difference between a board that runs a launcher and a board that holds a certified, credential-locked stack only becomes visible after the first field update.
Documentation closes the list. Buyers in Bern have learned to ask for the test reports before the deposit, because a CE mark printed on a carton is worth nothing at the port without the Declaration of Conformity behind it. AndroidSBC moves all three risks inside the factory: the custom variant is assembled at Longgang, the certified image is burned on the same line, and the Technical File ships with the lot. Across the nine WF-C3588 variants the coverage runs from edge AI inference boxes, AI gateways, machine vision inspection, video analytics appliances, smart city nodes, factory AI retrofits, and edge computing servers, with three memory configurations per variant, so a Bern buyer can usually match a requirement from the standard custom range.
Buyers in Switzerland tend to ask about the local mark before they ask about price. In Switzerland the market follows CE-aligned rules without EU membership, and OFCOM registration applies to radio equipment. AndroidSBC handles that by preparing the destination-market file covering CE-aligned conformity with OFCOM radio interface registration administered by OFCOM alongside the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), with the lot routed through Port of Rotterdam as the inland gateway on the Rotterdam to Yantian lane.
Competitive Comparison: WF-C3588-E7 vs Competing RK3588 Boards
Three families of board chase the same custom edge ai computing board 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-E7 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 GPU entry servers: the WF-C3588-E7 runs multi-model INT8 pipelines at a fraction of the power, which is what makes an unattended edge cabinet viable.
- vs cloud-analytics appliances: inference stays local on the 6 TOPS NPU, so the site keeps running when the uplink does not.
- vs NPU-less gateways: the board replaces the gateway plus a separate vision box with one SKU and one firmware line.
- vs assembled white boxes: Longgang validates the NPU runtime, the thermal profile and the appliance chassis together before the lot ships.
Global Custom Edge AI Computing Board Market Trends
The Custom Edge AI Computing Board curve is what Switzerland importers read before committing to a custom edge ai computing board programme. The number they quote is 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, Edge AI Hardware Market Report, 2025-2030), which serves as the closest public proxy for the silicon demand behind custom RK3588 boards. For Bern that resolves into three demand patterns across the WF-C3588 order book:
- Retail analytics box: a mall operator counts dwell time and demographics locally across hundreds of fanless nodes.
- Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-E7 board carries that headroom without a board change.
- Smart city intersection: a traffic programme runs vehicle and pedestrian analytics on one sealed node per junction.
For the Custom Edge AI Computing Board category the practical signal in Switzerland is that framework agreements are replacing spot buying, and the agreements are getting longer.
Across those three segments, Bern procurement has been shifting from spot quotes to framework agreements with a one-lot-per-month cadence, particularly where a custom Android, industrial, signage or robotics programme needs a twelve-month shipping window.

Field Report: a retail chain signage refresh across Bern, where 19,645 units of the WF-C3588-E7 board replaced legacy players in store windows
Reporter Mao Yi, on the ground in Bern, Switzerland. Crews worked store by store overnight so trading hours were never interrupted. The WF-C3588-E7 boards took the estate content package on first boot and reported back to the CMS within the hour. The chain's marketing team re-cut the window loop at 4K once the fleet was live, because the old players had capped it at 1080p.
A carton-level audit matched 40 sampled serials against the burn-in database with no mismatch.
The inspection confirmed three things on the spot: the WF-C3588-E7 units hold the burn-in with a yield above 99.35 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 CE-aligned conformity with OFCOM radio interface registration administered by OFCOM, cleared for entry at Port of Rotterdam as the inland gateway on the Rotterdam to Yantian 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 Switzerland importers can hand straight to their customs broker.

WF-C3588-E7 Application Scenarios
The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-E7 (Custom Edge AI Computing Board) as the lead SKU for Bern and Switzerland programmes:
- Retail analytics box: a mall operator counts dwell time and demographics locally across hundreds of fanless nodes.
- Factory vision retrofit: an assembly line adds defect classification without touching the PLC, using the multi-model pipeline.
- Smart city intersection: a traffic programme runs vehicle and pedestrian analytics on one sealed node per junction.
- Power grid substation: a utility reads gauges and thermal cameras locally over dual GbE back to the SCADA room.
- Agriculture edge node: a farm runs crop and pest models offline where connectivity is seasonal at best.
- Healthcare kiosk analytics: a clinic chain triages queues with on-device vision and no personal data leaving the site.
- Campus safety system: a university estate runs perimeter and corridor analytics with local alarm relay.
- Transit hub appliance: a station operator streams platform analytics to a control room over the optional 5G seat.
Partnership Models for Bern Buyers
For Bern distributors and brand owners, AndroidSBC opens the custom edge ai computing board line under three contract shapes:
- 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.
Whichever structure a Switzerland partner selects, the lot leaves Longgang with the same certification pack and the same test flow. The standard entry point on the WF-C3588-E7 is the 16GB + 64GB (WF-C3588-E7-C) configuration at MOQ 5,000 units per shipment, 1-3 days to sample and 15-30 days to mass production.
Frequently Asked Questions
What exactly can be customised on an RK3588 motherboard from AndroidSBC?
Answer: The customization scope runs across five layers: hardware (PCB, PCBA, I/O, memory, storage), thermal (fanless passive, vented, wide-temperature, conformal coating), software (custom ROM, custom Linux, pre-installed apps, OTA), branding (logo, packaging, boot animation, SKU labels), and compliance (the certification file assembled for the exact configuration you ship). Most Switzerland partners change two or three layers on a standard variant rather than commissioning a full custom run.
Can AndroidSBC port a custom Android ROM or a custom Linux BSP to our carrier board?
Answer: Custom ROM, custom BSP and custom SDK work are all part of the ODM tier. AndroidSBC builds the Android image (12, 13, 14 or 15, GMS or AOSP), ports the Linux BSP to your carrier revision, and releases the SDK modules your team needs under NDA. The engineering desk carries the port itself, so a Switzerland integrator is not left debugging an unmodified vendor BSP against a carrier it was never designed for.
Can the 6 TOPS NPU on a custom board run our own AI models?
Answer: Yes. The RK3588 NPU runs INT4, INT8, INT16, FP16, BF16 and TF32, and AndroidSBC supports model deployment through the Rockchip RKNN-Toolkit2, with quantization from PyTorch, ONNX, TensorFlow, Caffe and MXNet. As part of the ODM tier, the engineering desk walks your model from framework to RKNN format and validates it on the actual board configuration you are shipping, not a reference unit. Model files are versioned so a retrained model can be pushed to field units through OTA without a board swap.
What are the MOQ and lead times for a custom RK3588 motherboard?
Answer: The structure is deliberately two-speed: 1-3 days for a standard-variant sample so a Switzerland project team can start immediately, and 15-30 days to mass production on a custom run once the design freezes. MOQ is 5,000 units per shipment on standard variants, with custom and pilot quantities negotiated against the annual volume commitment.
What certifications does a custom board need for Switzerland, 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: The commitment is seven years minimum on supply, with security patches back-ported across the Android and Linux firmware tracks and OTA infrastructure for pushing firmware and RKNN model updates to deployed units. Long-lifecycle programmes in industrial, signage and robotics usually ask for the term in writing, and it is written.
Can AndroidSBC ship custom boards to Amazon FBA warehouses or 3PL consolidation points?
Answer: Yes. AndroidSBC ships DDP to Amazon FBA warehouses in the US, EU and Japan, and to nominated 3PL consolidation points in Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Carton labelling and pallet configuration follow FBA inbound requirements, the export declaration names the Wanlin Longgang source factory as the place of origin, and each pallet carries a per-unit barcode that traces back to the burn-in record for downstream RMAs.
How does AndroidSBC handle RMA or DOA replacements on custom boards?
Answer: Target DOA is 0.3 percent across twelve months. RMA works by returning the WF-C3588-E7 unit to Longgang with its burn-in barcode; replacements ship inside ten business days. Since each unit is traceable to its burn-in and configuration record, partners typically receive a root-cause note with the replacement rather than a silent credit.
