Sipeed Tang Primer 25K

The Sipeed Tang Primer 25K is a compact core board (23x18mm) built around the GW5A-LV25MG121 FPGA, paired with a 25K Dock base board that exposes all pins except MIPI high-speed pins.

The ultra-small core board size makes it ideal for any space-constrained applications. The versatile base board can be connected to a USB joystick, a 40-pin SDRAM module, and three PMOD interfaces for an HDMI display. It also supports a PS2 joystick, perfect for creating a RetroGame console setup. Additionally, it can be integrated with Sipeed's PMOD modules, making it suitable for FPGA university teaching.

The base board is equipped with both a USB A (Host, USB1.1) and USB C connector, along with a high-speed debugger.
