Overview
Tang Primer 25K is a minuscule core board (23x18mm) designed based on GW5A-LV25MG121, accompanied by a 25K Dock base board that exposes all pins (excluding MIPI high-speed pins).
The ultra-small core board size can be applied in any volume-restricted scenarios.
The simple base board can connect a USB joystick, plug in a 40Pin SDRAM module, and three PMOD interfaces can connect to an HDMI display, PS2 joystick to form a typical RetroGame console configuration.
It can also be paired with the series of PMOD modules produced by Sipeed, for use in FPGA university teaching.
