MangoPi-Nezha MQ: Low-Cost RISC-V SBC (39$)

MangoPi-Nezha MQ is a tiny open-source RISC-V development board that integrates Wi-Fi connectivity and dual USB Type-C ports into just 40mm x 40mm board. This is developed by RT-Thread, the organization involved building low footprint RTOS for various processors.

Powered by the Allwinner D1s chip, MangoPi board has support for display interfaces like RGB, DSI, and LVDS. It also includes onboard silicon microphones and class-D amplifiers for audio output(1W).

Software Support

MangoPi-Nezha MQ runs Tina Embedded Linux, an OpenWrt-based embedded system. With LVGL open-source graphics library, this platform allows you to take full advantage of the board’s hardware features for building application such has HMI, high performance machine controllers, etc. An optimized Debian Linux distribution is available as well.

RT-Thread has implemented support for xboot and RT-Smart, a high-performance microkernel operating system for professional, real-time applications. RT-Smart provides an open-source foundation for all kinds of embedded devices, whether you’re working in consumer electronics, security, industrial control, etc.

Microkernels fill the gap between traditional real-time operating systems (RTOSs) and heavier solutions like Linux. As a result, platforms like RT-Smart tend to do a better job of balancing real-time performance, cost, security, and startup speed.

If you are new to RISC-V, MangoPi-Nezha MQ Board could be a great board to start your entry into RISC-V world with embedded Linux.
