Development board
GitHub download.
This board can be used with the GD32F103Rx, GD32F303Rx and the GD32F107Rx, GD32F207Rx, GD32F407Rx (Ethernet) MCU's.
Please note that the crystal for the GD32F107Rx, GD32F207Rx and the GD32F407Rx is 25MHz and the crystal for the GD32F103Rx and GD32F303Rx is 8MHz.
The USB is power and DFU (Ethernet MCU only).
The 2x13 header is pin compatible with the Orange Pi Zero and Raspberry Pi boards. The 1x13 header is pin compatible with the Orange Pi Zero.
