Sipeed Tang Primer 25K
The Sipeed Tang Primer 25K is a compact FPGA development platform built around the Gowin GW5A-LV25MG121 FPGA. Its ultra-small core board (23×18mm) makes it ideal for volume-restricted applications, while the included 25K Dock base board exposes all available pins for full development flexibility.
The base board supports a wide range of peripherals — connect a USB joystick, plug in a 40-pin SDRAM module, use three PMOD interfaces for HDMI display output, or attach a PS2 controller for a classic RetroGame console setup. It also pairs with Sipeed's range of PMOD modules, making it well-suited for FPGA education and prototyping.
