SHENZHEN, China, September 12, 2026 - Wanlin Longgang released a 8,335-unit WF-C3588-E7 lot for Zagreb, Croatia this week, the 272nd run booked against the Rockchip RK3588 allocation.
AndroidSBC shipping and Incoterm briefing for WF-C3588 custom board orders serving Zagreb, Croatia. 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 Zagreb and Croatia 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 Croatia importers, the line covers the custom board categories a Zagreb 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 Croatia 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 Croatia Buyers
The recurring problem for Zagreb and Croatia 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 8,335-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 Zagreb 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 Zagreb buyer can usually match a requirement from the standard custom range.
Compliance for Croatia is handled at the factory rather than after arrival. In Croatia the market is small enough that most volume moves through distributors who also cover Slovenia and Serbia from one warehouse. The Longgang export desk builds the destination-market file for CE marking with HAKOM radio interface notification administered by HAKOM and issues it alongside the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), with the shipment booked into Port of Rijeka on the Rijeka to Piraeus relay.
Competitive Comparison: WF-C3588-E7 vs Competing RK3588 Boards
Three groups of board compete for the custom edge ai computing board socket. The first is catalogue silicon sold on price with no customization route and no certification file. The second is re-badged stock where the seller cannot produce a schematic or a test report. The third is a genuine custom platform on Rockchip RK3588 with the engineering desk, the burn-in rack and the certification file in one Longgang building. The WF-C3588-E7 sits in the third group.
- 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 market is the frame that decides how Croatia importers time their custom edge ai computing board orders. The figure most Croatia buyers quote when they argue about allocation is the Edge AI hardware segment, which MarketsandMarkets sizes 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); it is the public proxy for the RK3588-class silicon that custom board buyers compete for, not a forecast for this category. For Zagreb, three buying patterns are shaping 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 Croatia is that framework agreements are replacing spot buying, and the agreements are getting longer.
In all three cases, Zagreb buyers are converting spot quotes into blanket orders with a monthly lot release, because a custom motherboard programme that has to hold a twelve-month shipping window cannot tolerate a mid-year allocation break.

Field Report: burn-in room at the Wanlin Longgang plant running a 72-hour continuous loop on 8,335 units of the WF-C3588-E7 board, with rack-wide output monitored by an automatic pattern checker
Reporter Lin Yu, on the ground in Zagreb, Croatia. The burn-in room runs pattern generators that alternate between HDR10 and HLG material. Each WF-C3588-E7 unit carries a barcode tracked across the full 72-hour loop, and the rack controller issues a remote reboot whenever a unit shows an intermittent response on the I/O header.
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 marking with HAKOM radio interface notification administered by HAKOM, cleared for entry at Port of Rijeka on the Rijeka to Piraeus relay. Wanlin remains one of the few source factories currently shipping a nine-variant custom RK3588 motherboard line with a per-lot paper trail that Croatia 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 Zagreb and Croatia 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 Zagreb Buyers
For Zagreb importers and brand owners, the WF-C3588-E7 and the rest of the WF-C3588 custom variants are available 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.
Every tier draws on the same Longgang line and the same certification desk. A Zagreb first order on the WF-C3588-E7 normally lands on the 16GB + 64GB (WF-C3588-E7-C) configuration at MOQ 5,000 units per shipment, with standard samples in 1-3 days and a 15-30 day mass-production window on custom builds.
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 Croatia 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 Croatia 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 Croatia, 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 Croatia integrator running a custom configuration actually needs.
