RT-Thread is launching a Crowd Provide marketing campaign concentrating on builders all for studying about RISC-V and Microkernels. The Mango-Pi-Nezha MQ is a RISC-V-based single-board pc working Tina Linux. This tiny board is supplied with twin USB-C connectors, Wi-Fi, a number of flat ribbon interfaces, GPIO pins, and lots of different options ideally suited for embedded growth.
RT-Thread selected an Allwinner D1s/F133-A system-on-a-chip (SoC) to energy the MangoPi-Nezha MQ. This RISC-V chip incorporates a C906 core with a clock velocity of 1 GHz and 64 megabytes of DDR reminiscence. A number of months in the past, when RT-Thread teased the MangoPi, some studies mistakenly described the chip because the D1. The D1s is comparable however is a cost-reduced chip with much less RAM and no HDMI assist.
MangoPi-Nezha MQ measures 40 by 40 millimeters. Both sides of the sq. circuit board incorporates connector interfaces on each the highest and backside of the board. Moreover, there may be an antenna connector for Wi-Fi, which comes from an RTL8189 module hooked up to the again of the board.

Different connectivity contains two 22-pin GPIO headers, microphone, class-D audio output, micro SD card slot, and a number of flat ribbon cable (FPC) connectors. The FPCs assist interfaces just like the Raspberry Pi’s digital camera DSI, generic capacitive contact interfaces, and LVDS gadgets. Behind the micro SD card slot are solder-able pads so as to add an non-compulsory programmable-ROM chip.
For software program, RT-Thread says the MangoPi runs Tina Linux. This distribution is Allwinner’s OpenWrt-based embedded Linux. Alternatively, RT-Thread says the MangoPi additionally helps xboot and RT-Good, that are microkernels that fill the hole between conventional real-time working techniques (RTOS) and full Linux kernels.
With a bevy of interfaces in such a compact dimension, the MangoPi-Nezha MQ appears to be like like a wonderful platform for studying embedded applied sciences like RISC-V and Microkernels. Each the RT-Good Microkernel and {hardware} designs are open supply. The KiCad recordsdata are already accessible within the MQ GitHub repository.
Primarily based on this December 2021 tweet, it seems MangoPi is already going by manufacturing. So to know when the Crowd Provide marketing campaign launches, head over the MangoPi-Nezha MQ marketing campaign web page and join updates.
