MangoPi-Nezha MQ is an open-source RISC-V development board that integrates Wi-Fi connectivity and dual USB Type-C ports into one tiny (4x4 cm) package. Powered by the Allwinner D1s chip, it provides support for rich display interfaces like RGB, DSI, and LVDS. It also includes onboard silicon microphones and class-D amplifiers for audio output.

The RISC-V open-source instruction-set architecture (ISA) has reached a turning point. We invite you to join a community that is growing like crazy!

Firmware & Software

MangoPi-Nezha MQ runs Tina Linux, an OpenWrt-based embedded system. Combined with the LVGL open-source graphics library, this platform allows you to take full advantage of the board’s hardware features. An optimized Debian Linux distribution is available as well.

We’ve also 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, or some other sector that relies on embedded technology (which, these days, is pretty much every sector). 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.

And if you’re new to these technologies, MangoPi-Nezha MQ is not only a perfect way to get started with RISC-V, it’s also a great introduction to Linux and to microkernels!

Manufacturing Plan

We have tested MangoPi-Nezha MQ thoroughly and are extremely confident, both in the quality of the product and in the viability of the overall project. We’ve made arrangements with our manufacturing partner to ensure that we will be in a position to begin production immediately following a successful campaign.

Fulfillment & Logistics

After testing and packaging the production batch of MangoPi-Nezha MQ boards, we will send them on to Crowd Supply’s fulfillment partner, Mouser Electronics, who will distribute them to backers worldwide. You can learn more about Crowd Supply’s fulfillment service under Ordering, Paying, and Shipping in their guide. Unfortunately, we are unable to sell MangoPi-Nezha MQ to backers in Europe, as it is not CE marked.

Risks & Challenges

While we’ve done a great deal of preparation to ensure that production goes smoothly, there are always uncertainties in a project like this. Shipping delays due to circumstances out of our control are the most significant risk we currently face, but we’re working closely with our suppliers, our manufacturing partners, and Crowd Supply to mitigate these risks and to maximize our efficiency despite the challenges presented by the current state of global supply chains.
