The DongshanPI-D1s development board is comprised of a soldered-on Allwinner D1s RISC-V system-on-module board (SoM) and a carrier board with two 40-pin headers and a 2.0mm dedicated header. This development board is specifically designed to teach programming with a focus on the RISC-V architecture.
The development board was designed by 100ask. They previously designed the Dongshan NeZha STU a development board based on the Allwinner D1. The main difference between the two is that 100ask did not include the Ethernet and HDMI interfaces on the DongshanPI-D1s board. The pinout of the headers is also slightly different because they opted to make the headers compatible with the widely used 40-pin GPIO from Raspberry Pi single board computers.
