Tang Primer 25K is a core board with a very small package (23x18mm) designed based on GW5A-LV25MG121, and is equipped with a 25K Dock baseboard with full pin lead-out (except MIPI high-speed pins). Tang Primer 25K core board is a compact and highly integrated FPGA core board. It integrates Gaoyun GW5A-LV25MG121, 64Mbit SPI FLASH, DC-DC power supply and BTB connector in an area smaller than a one-yuan coin. The core board leads out 76 GPIOs, 1 hard-core 4lane MIPI line and 3 power outputs for users to use. Users only need to provide a 5V power supply to the core board and correctly set the configuration pins to easily use the Tang Primer 25K core board. Tang Primer 25K Dock baseboard is a generation of modular baseboard, equipped with an easy-to-use USB-JTAG debugger, 3 PMOD interfaces and 1 40P pin header interface. Users can use the PMOD interface to connect simple modules such as HDMI modules, handle modules, and LED modules. In addition, users can also use the 40P pin header interface to connect SDRAM modules, dual DVP camera modules and other modules with more complex functions. Compared with the common FPGA development environment on the market, the IDE installation package required by Tang Primer 25K is less than 200MB in size; the space occupied after installation is close to 500MB, which greatly saves hard disk space. The IDE usage process is extremely streamlined and beginners will not be overwhelmed by too many options. Compared with other IDEs on the market that program in five minutes and integrate in ten minutes, the IDE used by Tang Primer 25K can bring a pleasant experience of programming in five minutes and integrating in only ten seconds.
