This program summary is written for cross-border B2B buyers evaluating Rockchip RK3568 sourcing options from Chinese factories. Wanlin Group operates its own 12,000 m2 manufacturing facility in Shenzhen with 8 SMT lines, 4 AOI inspection stations and 2,400 m2 of cleanroom assembly, exporting Rockchip RK3568 boards to 60+ countries under the AndroidSBC brand. Total cost of ownership for an AndroidSBC Rockchip RK3568 deployment typically runs 35-50% below x86-based western players and 15-25% below comparable boards sourced through trading companies. For USA, this article maps the model line, the economics and the compliance route specific to your market.
Global Rockchip RK3568 Board Market Overview and 2026 Buyer Demand
The single board computer market is estimated at USD 3.1 billion in 2025, projected to grow at 8.8% CAGR to USD 7.2 billion by 2035, with maker-to-production workflows pulling hobby-class hardware into commercial products.
Regional compliance for USA is anchored on FCC Part 15 Subpart B, UL 62368-1 safety evaluation and Google GMS licensing where Play Store distribution is required. Cross-border buyers are advised to verify the certification scope and software build of every board before import, since some China-supplied boards ship without destination radio approval or without the licensed Android build the project actually needs, and either gap can stall customs clearance or store audits.

Rockchip RK3568 Application Scenarios across SBC Sites
The Rockchip RK3568 boards below run in live deployments on five continents. Each entry cites the site, the unit count and a measured outcome rather than a capability claim.
Scenario 1: agritech sensor gateways (Tel Aviv, Israel). An agritech startup runs 400 WF-RK3568-SB510 boards as field gateways for irrigation sensors. Boards log locally, sync over 4G on schedule, and run on solar kits through the growing season. Measured result: field swaps dropped to 3 units across a full season.
Scenario 2: maker education program (Seoul, South Korea). A maker education company kits 150 school labs with WF-RK3568-SB510 boards. Curriculum ships on the board image, and students progress from GPIO blink lessons to camera projects on the same hardware. Measured result: kit preparation for a 30-seat lab takes 40 minutes.
Scenario 3: university robotics lab fleet (Berlin, Germany). A university robotics lab runs 300 WF-RK3568-SB510 boards as compute nodes for student robot builds. The GPIO header drives motor shields, and the lab images boards centrally at the start of each semester. Measured result: board attrition across two semesters stayed under 2%.
Scenario 4: smart office pilot racks (Singapore). A facilities firm runs 60 WF-RK3568-SB510 boards in a living-lab rack testing occupancy and desk-booking services. Boards reboot on test schedules and stream logs to the analytics cluster. Measured result: test cycle turnaround fell from 2 weeks to 2 days.
Scenario 5: drone telemetry ground stations (Vancouver, Canada). A surveying company built 18 WF-RK3568-SB510 ground stations for drone telemetry. Boards ingest live video and flight data, log to SSD, and mirror the feed to site tablets over a local hotspot. Measured result: station boot-to-ready reached 35 seconds.
AndroidSBC Rockchip RK3568 Competitive Advantages for Cross-Border Buyers
The WF-RK3568-SB510 and the broader AndroidSBC Rockchip RK3568 portfolio deliver eight distinct advantages for cross-border B2B buyers sourcing Android boards directly from Chinese manufacturers:
- Source-factory pricing - Wanlin operates the SMT lines, so FOB Shenzhen pricing runs 15-25% below trading-company resale and 35-50% below western x86 players.
- Platform engineering - 4x ARM Cortex-A55 up to 2.0 GHz, 64-bit with Mali-G52 2EE GPU, OpenGL ES 3.2, engineered in Shenzhen rather than rebadged from a broker.
- Hardware 4K@60fps H.265 / VP9 decode - Hardware 4K@60fps H.265 / VP9 decode, 1080p@60fps encoding, at a cost point set for volume deployments.
- Full display interface coverage - HDMI 2.0 + LVDS + eDP + MIPI-DSI, dual-display independent output, supporting panels from 7 to 86 inches with factory panel-config and backlight driver onboard.
- Dual-OS flexibility - Android 11 / Linux (Debian, Yocto, Ubuntu) dual-OS images with Ubuntu / Debian / Yocto Linux images serves both app-driven and Linux-BSP projects from one board.
- Custom memory/storage - 2GB-8GB LPDDR4 / 16GB-128GB eMMC configurable, matching image size and workload to deployment need.
- ODM depth - carrier board redesign, custom I/O, custom enclosure, AOSP build and Linux BSP porting from one factory.
- Continuous-duty reliability - hardware watchdog, RTC, scheduled power on/off, auto-reboot and wide-temperature trim for commercial and industrial duty.
Combined, these advantages let AndroidSBC Rockchip RK3568 partners win operator contracts, signage tenders, gateway programs and industrial projects, secure regional distribution rights, and serve end customers under their own brand at a landed cost 35-45% below legacy western suppliers.
Rockchip RK3568 Certifications, Standards Route and Regional Compliance
The WF-RK3568-SB510 carries the following certifications as standard scope: CE / FCC / RoHS / REACH / UKCA. Optional add-on documentation available on request includes UKCA, KC, PSE, SAA, RCM and EAC packs, country-specific declaration templates, UL 62368-1 test reports and extended-temperature test reports for industrial builds. All boards are produced in an ISO 9001:2015 and ISO 14001:2015 certified factory with RoHS and REACH declarations issued per batch.
Cross-border buyers should note that board compliance is a combination of product marking, radio certification, safety evaluation and - where Play Store distribution is required - Google GMS licensing. For USA specifically, importers should confirm FCC Part 15 Subpart B, UL 62368-1 safety evaluation and Google GMS licensing where Play Store distribution is required before shipment. Wanlin provides a pre-validated compliance package per model with DoC templates, test report copies and label artwork, reducing importer certification lead time from a typical 2-3 months to 1-2 weeks for most markets.

Rockchip RK3568 Board Export FAQ - OEM, ODM, MOQ, Lead Time, Partnership
Below are eight frequently asked questions from cross-border buyers sourcing Rockchip RK3568 boards from China. Each answer is anchored on Wanlin's actual commercial terms, certification scope and field experience across 60+ export markets under the AndroidSBC brand.
What is the difference between OEM and ODM for Rockchip RK3568 boards?
Answer: OEM (Original Equipment Manufacturer) means Wanlin Group builds the Rockchip RK3568 board, core board or finished device under your brand with your PCB silk-screen, logo, packaging and SKU. ODM (Original Design Manufacturer) means we redesign the carrier board, memory/storage combo, I/O set, firmware or enclosure around your project. Both run from the same Shenzhen factory and the same BSP team: OEM lead time is 12-20 days and ODM 30-45 days including pre-compliance checks. Schematic review, custom carrier layout, AOSP or Linux build work and certification support are provided under NDA.
Which Rockchip RK3568 board should I source for my application?
Answer: Eight selection rules for cross-border buyers:
- (1) OTT / IPTV / streaming boxes: WF-RK3568-TV110 with the media pipeline and IR wake-up.
- (2) Digital signage and advertising machines: WF-RK3568-DS210 with dual display and CMS agents.
- (3) Commercial displays, information publishing and kiosk back ends: WF-RK3568-CD310 with LVDS / eDP panel support.
- (4) Touch all-in-ones, smart screens and smart mirrors: WF-RK3568-SD410 with MIPI-DSI + 10-point touch.
- (5) Maker SBCs, Linux hosts and prototyping: WF-RK3568-SB510 with GPIO header and dual-OS images.
- (6) Smart home hubs, IoT gateways and building automation: WF-RK3568-IG610 with RS485 / CAN and radio options.

- (8) Thin clients, VDI terminals, education labs and NAS: WF-RK3568-TC810 with cloud desktop agents.
What software support comes with the boards?
Answer: Every family ships with Android and Linux images, BSP source access, SDK documentation and OTA tooling. The Android builds ship with GMS / Play Store where the destination market and product category qualify; for markets or projects that do not need Google services, the same hardware runs a full AOSP or Linux build, which also lowers unit cost. Wanlin manages the approval paperwork against your brand and hands over the listing evidence before mass production.
How do Wanlin Rockchip RK3568 boards compare with NXP i.MX 8M Mini, Texas Instruments AM62x and Rockchip RK3566 class boards?
Answer: The Rockchip RK3568 is positioned as a source-factory platform: because Wanlin builds the boards rather than reselling them, landed cost typically runs 15-25% below comparable boards sourced through trading companies and 35-50% below western-branded equivalents. On the engineering side, the Rockchip RK3568 brings 4x ARM Cortex-A55 up to 2.0 GHz, 64-bit with hardware 4k@60fps h.265 / vp9 decode, and the BSP covers Android 11. Where a project needs certified Android with Play Store, the GMS option closes the software gap at the same hardware cost.
Can the same board run Android and Linux, and how does dual-OS work?
Answer: Yes. Every Rockchip RK3568 family ships Android images alongside Linux support (Ubuntu, Debian and Yocto-based builds). Dual-OS means we can flash Android to the onboard eMMC and provide a Linux image for TF-card boot, or ship a dual-partition image that selects the OS at power-up. For industrial and gateway projects we pre-load a Linux BSP with device tree, drivers and SDK; for TV, signage and display projects the default image is Android with the launcher, CMS agent or desktop client you specify.
What are the MOQ, lead time, trade terms, sample policy and warranty?
Answer: MOQ is 100 pcs per model. Lead time is 12-20 days for standard configurations and 30-45 days for ODM customization. Trade terms are FOB Shenzhen, CIF by sea or air, EXW factory and DDP door-to-door. Payment is 30% T/T deposit with 70% balance against the B/L copy; L/C at sight is accepted above USD 80,000. Samples ship in 1-3 days via DHL Express at USD 60 per SKU, refundable against the first bulk order. Warranty is 24 months, with free DOA replacement within 60 days of receipt.
Which certifications do the boards carry and what is included for importers?
Answer: Boards ship with CE / FCC / RoHS / REACH / UKCA declarations per batch from an ISO 9001:2015 and ISO 14001:2015 certified factory. UKCA, KC, PSE, SAA, RCM, EAC and UL 62368-1 report documentation is available on request, and FCC Part 15 Subpart B, UL 62368-1 safety evaluation and Google GMS licensing where Play Store distribution is required. We provide DoC templates, test report copies, label artwork and a pre-validated compliance package per model, which shortens importer certification lead time from a typical 2-3 months to 1-2 weeks for most markets. Industrial boards can add conformal coating and extended-temperature test reports.
What customization and partnership options does Wanlin offer?
Answer: Customization scope:
- (1) Branding - custom PCB silk-screen, private-label logo on board and enclosure, custom SKU and packaging.
- (2) Firmware - boot logo, boot animation, pre-installed apps, custom launcher, locked-down kiosk builds.
- (3) Hardware - carrier board redesign, custom I/O, memory and storage combos (2GB-8GB LPDDR4 / 16GB-128GB eMMC configurable), WiFi/BT module selection, 4G/5G radio options.
