Tang Primer 25K is a very small package core board designed based on GW5A-LV25MG121. The extremely small core board size can be applied to any volume-limited scenario. Tang Primer 25K core board is a compact, highly integrated FPGA core board. It integrates Gowin GW5A-LV25MG121, 64Mbit SPIFLASH, DC-DC power supply and BTB connector in an area smaller than a one-yuan coin. The core board leads to 76 GPI0, 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. Note:Due to different production batches, the appearance is different, which does not affect the use.
