The RK3506J Mini SBC is aimed at the developers, who require a small and power efficient platform to use in industrial and IoT applications. This board is based on the Rockchip RK3506J and combines three Cortex-A7 cores up to 1.5 GHz and a Cortex-M0 coprocessor. Combination of performance and efficiency make it applicable to use in control systems, edge devices and automation projects where space and power constraints are high.
To support this increased need of low-power embedded computing, Forlinx designed this SBC as the OK3506 series. It is designed with a view of providing flexible interfaces and long-term availability to the developers along with a software environment that minimizes the time to market. The small size, minimal heat dissipation and efficient storage management is an added value in terms of deployment in applications that need reliability.

The RK3506J Mini SBC is based on the Rockchip RK3506J processor that integrates three Cortex-A7 cores with a maximum frequency of 1.5 GHz with a Cortex-M0 coprocessor. It is the perfect choice on the way to lightweight computing and real-time control because this architecture provides an effective compromise between low power consumption and performance. The board comes with 256 MB or 512 MB of DDR3 memory and has board NAND storage space options of 256 MB or 512 MB. Growth is facilitated by a Raspberry Pi-compatible 40-pin GPIO header which provides the developer with the option of connecting a broad array of peripherals.
On the connectivity side, the SBC provides two USB 2.0 ports, RMII Ethernet, UART, I²C, SPI, and CAN-FD, covering both everyday and industrial communication needs. For display support, it integrates MIPI-DSI and RGB888 interfaces with resolutions up to 1280 x 1280 at 60 Hz. Additional options include FlexBUS and DSMC parallel bus connections for industrial peripherals, while the Matrix I/O system enables up to 98 functions to be assigned across 32 pins for more complex designs.
Optimized for industrial applications, the RK3506J Mini SBC consumes just 0.7 W under load, removing the need for extra cooling hardware. Reliability features such as eMMC health diagnostics and tuned storage drivers extend the board’s operational lifespan in demanding environments. With a long-term supply guarantee of 10 to 15 years, the platform offers a dependable foundation for IoT gateways, automation systems, and embedded product development.

Board supports Linux 6.1 BSP with real time extensions, asymmetric multiprocessing and GUI systems like LVGL. The improved storage management features, such as eMMC health monitoring, can also be useful to developers to enhance the reliability of the devices operating 24 hours a day in an industrial setup. The software stack can be developed fast, and it can be combined with sensors, displays, and communication protocols without the need to do a very extensive customization.
The RK3506J Mini SBC is being sold by Forlinx and its distributors. There are different configuration pricing depending on the memory and storage capacity. A typical single unit order of a standard model with 512 MB RAM and NAND storage costs around 100 dollars at normal prices and in large quantities can be discounted. The developers may also approach Forlinx directly to make quote requests based on the requirements of their project and shipping location.
