TL;DR: RK3588 PCIe 3.0 Custom Expansion Board
SHENZHEN, China, September 12, 2026 - Wanlin Manufacturing Group pushed lot 269 of the WF-C3588-E7 board out of the Longgang plant this week, 32,840 units for Santiago, Chile, with the export declaration naming Longgang as the place of origin.
AndroidSBC unveils the nine-variant custom RK3588 motherboard line spanning custom Android boards, industrial boards, core boards and SOMs, signage, kiosk, robotics, NVR, edge AI and ARM PC work serving Santiago, Chile. AndroidSBC is releasing the full WF-C3588 custom motherboard line for Santiago and Chile: nine variants built on the Rockchip RK3588 octa-core 6 TOPS NPU platform, covering custom Android motherboards, custom industrial boards, core board and SOM carrier design, 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. The line ships from the Wanlin Longgang facility with OEM branding, ODM carrier work, and per-lot CE, FCC, UKCA, RoHS and IEC 62368-1 documentation handled in-house.

About AndroidSBC and the Rockchip RK3588 Board Family
The WF-C3588 exists because Chile buyers kept asking one supplier for two different custom board tiers. Wanlin Manufacturing Group answered by putting nine custom variants on the same Rockchip RK3588 octa-core silicon with 6 TOPS NPU, 8K H.265 video and up to 32GB of LPDDR5. The group runs SMT, burn-in and pre-compliance testing in one Longgang building in Shenzhen, and the export desk holds the certification file rather than passing it back to the importer. For a Santiago distributor that means one vendor file, one document format and one MOQ structure across the custom variants it sells.
WF-C3588-E7 Technical Specifications
| Parameter | AndroidSBC WF-C3588-E7 (Custom Edge AI Computing Board) | Industry Average |
|---|---|---|
| Processor | Rockchip RK3588 octa-core 4x Cortex-A76 2.4GHz + 4x Cortex-A55 1.8GHz (8nm) + 6 TOPS NPU | Cortex-A55 gateway without NPU |
| NPU precision | INT4 / INT8 / INT16 / FP16 / BF16 / TF32 mixed precision | INT8 only |
| Model toolchain | RKNN-Toolkit2 quantization from PyTorch, ONNX, TensorFlow, Caffe and MXNet | Cloud-only deployment |

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 Chile 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 Chile Buyers
The custom edge ai computing board sourcing question that Santiago distributors keep coming back to is continuity across quarters. The Rockchip RK3588 requires a dedicated wafer slot, and a 32,840-unit order placed against broker inventory often turns into a two-month slip with no warning. Then comes the software layer. A board that boots is not a board that holds a certified stack under a 72-hour loop, and Chile buyers typically find the difference in their own warehouse rather than at the factory.
Documentation closes the list. Buyers in Santiago have learned to request the test reports before releasing the deposit, because a mark printed on a carton carries no weight at the port if the Technical File behind it does not exist. AndroidSBC handles it by doing the custom I/O build, the software burn and the documentation at the factory: every lot leaves Longgang with the certified image loaded, a unit-level burn-in barcode, and a Technical File that carries the test reports. The nine WF-C3588 custom variants cover 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 each, which means a Santiago integrator can usually match a customer requirement without a bespoke production run.
For Chile specifically, the file travels with the goods. In Chile SUBTEL homologation is required before the equipment can be offered for sale, and the importer of record carries that obligation. AndroidSBC prepares the SUBTEL type approval with SEC electrical conformity documentation for SUBTEL, attaches the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), and consigns the lot to Port of San Antonio on the San Antonio to Shanghai 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
Buyers in Santiago are reading the Custom Edge AI Computing Board curve before they commit to a custom edge ai computing board 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 Chile:
- 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.
Channel analysts tracking the Custom Edge AI Computing Board category note that allocation discipline, not unit price, has become the deciding factor for buyers who need a twelve-month programme to hold.
The common thread in Chile 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: Cedarline Media Networks in Santiago, Chile

Field Report: a school district rollout in Santiago, where 32,840 units of the WF-C3588-E7 board are being installed in classroom device carts
Reporter Sun Ming, on the ground in Santiago, Chile. The district took delivery of the order and dispatched installation crews to eight sites. Each WF-C3588-E7 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-E7 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-E7 units hold the burn-in with a yield above 98.72 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 SUBTEL type approval with SEC electrical conformity administered by SUBTEL, cleared for entry at Port of San Antonio on the San Antonio 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 Chile 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 Santiago and Chile 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 Santiago Buyers
The WF-C3588 custom line is available to Chile 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 Santiago first order on the WF-C3588-E7 is normally the 16GB + 64GB (WF-C3588-E7-C) 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 Chile partners iterate models without replacing hardware.
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 Chile 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 Chile, 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-E7 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 Chile integrator running a custom configuration actually needs.
