Sipeed Tang Primer 25K Core Board | Gowin GW5A RISC-V FPGA System-on-Module | For Portable Embedded & Display Prototyping
Description
SPIDER Automation Sipeed Tang Primer 25K SoM Board is a cutting-edge, highly integrated FPGA module designed to push the boundaries of compact hardware development. Built around the Gowin GW5A-LV25MG121 FPGA, this System-on-Module seamlessly combines high logic density, non-volatile 64Mbit SPI flash memory, and an efficient DC-DC power supply into a minuscule footprint smaller than a standard coin.
Designed for effortless system integration, the board utilizes a robust Board-to-Board (BTB) connector layout that exposes 76 versatile GPIOs, a hard-core 4-lane MIPI D-PHY interface for high-speed video applications, and three regulated power outputs. Requiring only a clean 5V supply to power the module, the Tang Primer 25K offers developers an exceptional, pocket-sized platform for building custom RISC-V processors, portable hardware accelerators, and advanced display controllers.
