## Description

The Sipeed Tang Primer 25K is a small core board (23x18mm) designed based on a GW5A-LV25MG121 FPGA and 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, use three PMOD interfaces to connect to an HDMI display, or plug in a 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.

The base board has both a USB A (Host, USB1.1) and USB C connector as well as a high-speed debugger.
