Long-term Supply Industrial Board, WF-RK3568, AndroidSBC, Zagreb

TL;DR: Long-term Supply Industrial Board

Zagreb, Croatia - September 10, 2026. A 13,410-unit consignment of WF-RK3568 boards left the Wanlin Longgang source factory for Zagreb this week, the 410th production lot released on the Rockchip RK3568 line.

AndroidSBC quarterly sourcing bulletin on Allwinner and Rockchip custom boards serving Zagreb, Croatia. AndroidSBC is opening the full WF-Series to Croatia: Allwinner A133, H618, and T527 on one side, Rockchip RK3588, RK3568, RK3566, and RK3288 on the other, plus WF-A133S and WF-RK3588S for carrier-board work. Every board ships from the Wanlin Longgang facility with OEM branding available, ODM carrier design handled in-house, and per-lot CE, FCC, UKCA, and RoHS documentation.

About AndroidSBC and the Rockchip RK3568 Board Family

Wanlin Manufacturing Group is a Shenzhen board builder that has worked on Allwinner and Rockchip silicon for more than ten years, and AndroidSBC is the name it sells under overseas. The WF-Series is the current line: nine boards spanning Allwinner A133, H618, and T527 and Rockchip RK3588, RK3568, RK3566, and RK3288, with two SOM modules for customers who bring their own carrier. Production, test, and packing sit in one Longgang building, which is why the group can issue a per-lot Technical File instead of a generic declaration. Buyers in Zagreb and Croatia usually arrive for one of three reasons: platform breadth, OEM branding capacity, or a supplier willing to carry the certification obligation.

WF-RK3568 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-RK3568 (Industrial Edge 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 4GB + 32GB (WF-RK3568-A) variant is the typical configuration for the industrial edge computing use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Industrial Edge Computing Board for Croatia Buyers

What breaks Croatia sourcing plans on the industrial edge computing board line is not price negotiation, it is the second shipment. The Rockchip RK3568 has to be allocated at wafer level, and the brokers quoting fastest are usually the ones with the least control over that allocation. Then there is the software build. A board that boots is not the same as a board that carries the certified stack a Croatia 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 Croatia customs officer asks for it. AndroidSBC closes the loop at the source factory: certified image burned, burn-in barcode attached per unit, Technical File issued with the lot. The nine WF-Series models cover industrial edge computing, commercial display controller, industrial HMI, IoT gateway, smart display terminal, machine monitoring, access control, and building automation and each ships in three memory configurations, so most Zagreb requirements can be met from standard stock rather than a custom production run.

For Croatia specifically, the file travels with the goods. In Croatia the market is small enough that most volume moves through distributors who also cover Slovenia and Serbia from one warehouse. AndroidSBC prepares the CE marking with HAKOM radio interface notification documentation for HAKOM, attaches the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), and consigns the lot to Port of Rijeka on the Rijeka to Piraeus relay.

Competitive Comparison: WF-RK3568 vs Competing RK3568 Boards

The boards competing for the same socket in the industrial edge computing board segment fall into three groups: low-cost legacy SoC boards without a certified software stack, mainstream Cortex-A55 boards with certification but a lower decoder ceiling, and 64-bit boards that carry both but stop short on expansion. The WF-RK3568 sits in the third group and adds three things: Rockchip RK3568, a display path that survives a continuous loop, and the per-lot certified image burn at Longgang.

• vs RK3288 Cortex-A17 boards: the RK3568 Cortex-A55 2.0GHz lifts integer throughput by roughly 2x at lower idle power.
• vs RK3566 boards: the RK3568 adds dual Gigabit Ethernet plus CAN bus for gateway-class builds.
• vs RK3588 boards: the RK3568 keeps a materially lower BOM where 4K@60fps decode is sufficient.
• vs x86 fan-cooled IPC: the RK3568 fanless design removes the only moving part from the enclosure.

Global Industrial Edge Computing and Smart Display Market Trends

The Industrial Edge Computing and Smart Display market sets the pace for Zagreb procurement this year, and it does not move on its own. The consumer Android TV Box segment that Global Growth Insights values at USD 12.45 billion in 2025, with a 30.49 percent CAGR reaching USD 178.2 billion by 2035 (Global Growth Insights, Android TV Box Market Report, 2025-2035), sets the silicon allocation backdrop that commercial board buyers also compete for. Three patterns stand out in the WF-Series order book for Croatia:

• Industrial edge computing: WF-RK3568 runs the edge workload on the 1 TOPS NPU with dual Gigabit uplinks.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-RK3568 board carries that headroom without a board change.
• Industrial HMI: WF-RK3568 holds the wide-temperature envelope with the fanless design.

The Industrial Edge Computing and Smart Display 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 Croatia is that single orders are being replaced by blanket agreements with a monthly release, because a programme that has to survive a twelve-month window cannot absorb an allocation gap in the middle of it.

Partner Success Story: Lumen Menu Systems in Zagreb, Croatia

Lumen Menu Systems, a quick-service restaurant technology vendor serving the Croatia market, deployed 6,900 units of the WF-A133 board for outdoor menu and order confirmation displays. The rollout covered the industrial edge computing, industrial hmi, and machine monitoring workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 6,900 units of the WF-A133 board for outdoor menu and order confirmation displays
• Region: Zagreb, Croatia
• Models used: WF-A133, WF-H618, WF-T527, WF-RK3588, WF-RK3568, WF-RK3566, WF-RK3288, WF-A133S, WF-RK3588S

Field Report: container yard at Yantian, where 13,410 WF-RK3568 boards from the Wanlin export base are being loaded onto containerised pallets with the customs declaration naming the Longgang source factory

Reporter Fang Yu, on the ground in Zagreb, Croatia. The yard crew handled the order on flat pallets wrapped in anti-static film, with every carton barcode-traced back to the burn-in record. The customs broker attached a single declaration naming the Wanlin Longgang source factory as the place of origin, and the container was sealed before the afternoon cut-off.

The line ran the WF-RK3568 boards through a 30-minute HDR10 loop at the inspection bench with no colour banding reported by the operator.

The inspection confirmed three things on the spot: the WF-RK3568 units hold the burn-in with a yield above 98.94 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-board Allwinner and Rockchip custom line with a per-lot paper trail that Croatia importers can hand straight to their customs broker.

WF-RK3568 Application Scenarios

The WF-Series fits nine application lanes, with the WF-RK3568 (Industrial Edge Computing Board) as the lead SKU for Zagreb and Croatia programmes:

• Industrial edge computing: WF-RK3568 runs the edge workload on the 1 TOPS NPU with dual Gigabit uplinks.
• Commercial display controller: WF-RK3568 drives the 4K@60fps panel pair over HDMI 2.0 and eDP.
• Industrial HMI: WF-RK3568 holds the wide-temperature envelope with the fanless design.
• IoT gateway: WF-RK3568 bridges CAN bus and RS485 field devices onto Ethernet.
• Smart display terminal: WF-RK3568 renders the Android 11 UI on the dual display path.
• Machine monitoring: WF-RK3568 timestamps production data against the onboard RTC.
• Access control: WF-RK3568 runs face recognition on the NPU with the MIPI CSI feed.
• Building automation: WF-RK3568 runs 7x24 with hardware watchdog and scheduled restart.

Partnership Models for Zagreb Buyers

The WF-Series is available to Croatia 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 REACH. A Zagreb first order on the WF-RK3568 is normally the 4GB + 32GB (WF-RK3568-A) configuration at MOQ 5,000 units per shipment, four weeks for samples and six weeks for mass production.

Frequently Asked Questions

Does the WF-Series support certified Android TV or Google Mobile Services?

Answer: It depends on the platform, and AndroidSBC is explicit about the split. The WF-H618 carries the ATV 12 GMS build with Widevine L1 and Dolby Audio pre-burned at the factory. The WF-A133, WF-T527, and the Rockchip boards ship with an AOSP or Linux image by default, and a GMS build can be prepared for ODM partners who need Play Services in the field. Certification scope is agreed per project rather than assumed.

What is the difference between the nine WF-Series models?

Answer: WF-A133 is the Allwinner A133 commercial display and advertising board. WF-H618 is the Allwinner H618 OTT TV box and Android TV board. WF-T527 is the Allwinner T527 octa-core industrial control and edge AI board. WF-RK3588 is the Rockchip RK3588 8K video wall and AI computing board. WF-RK3568 is the Rockchip RK3568 industrial edge board. WF-RK3566 is the Rockchip RK3566 machine vision and HMI board. WF-RK3288 is the Rockchip RK3288 POS and signage board. WF-A133S is an Allwinner A133 SOM module for custom carrier work. WF-RK3588S is a Rockchip RK3588 SMARC 2.2 module for the same purpose.

Can AndroidSBC handle CE, FCC, UKCA, RoHS, and REACH paperwork for Croatia?

Answer: Yes, and the file travels with the goods rather than behind them. The pack covers CE, FCC Part 15, UKCA, RoHS 2.0, and REACH with test reports dated within the prior year. AndroidSBC will also advise on any Croatia-specific addition during quotation, which is the point at which the answer is still useful.

What are the MOQ and lead time for a first order?

Answer: The entry point is 5,000 units per shipment, four weeks for samples and six weeks for production. A twelve-month framework agreement released monthly will bring the per-lot MOQ down, and AndroidSBC will accept a mixed order that draws several WF-Series boards against a single contract.

Does AndroidSBC support custom Android ROM or custom Linux development?

Answer: Yes, under NDA. ODM partners get custom Android ROM work including proprietary services and a custom launcher, Linux builds based on Yocto, Debian, or Buildroot, and BSP ports for custom carrier boards. The SDK and BSP source are released to the partner under the NDA, and AndroidSBC's engineering desk handles the port rather than handing over an unmodified vendor drop.

What about software updates and long-term support?

Answer: Wanlin commits to a minimum seven-year supply window across the WF-Series. Security patches are back-ported across the Android and Linux firmware tracks for as long as the board is in production, and AndroidSBC provides OTA update infrastructure for partners who need to push firmware to field-deployed units. For POS and industrial programmes, the support commitment is written into the framework agreement rather than left as an understanding.

Can AndroidSBC ship 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, and Los Angeles. 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?

Answer: The DOA target is 0.3 percent over twelve months. For RMA, partners send the WF-RK3568 unit back to Longgang with the burn-in barcode attached, and replacements go out within ten business days. The per-unit burn-in record means the failure report usually carries a root cause alongside the replacement.
