Description

This is a control board with onboard RISC-V microprocessor (GD32VF103), which belongs to the DockerPi series expansion board.
It communicates with the Raspberry Pi (or similar SBC) through I2C.
The factory program allows the user to control the changes of the two LEDs.
The software is fully open source, allowing users to program in JTAG mode.
There are 2 user indication LEDs, power LEDs, and all IOs.
It is suitable for coprocessors, analog conversions, low-power computing and other occasions.
Warning:

Please pay attention to the working characteristics of the microprocessor's GPIO during secondary development. Some pins cannot be compatible with 5V level, and some pins do not support high current drive.
The RISC-V architecture is very different from ARM.
You must read related manuals carefully before performing secondary development on it.
