Sipeed Tang Nano 20K FPGA Development Board, Open Source RISCV Linux Retro Game Player with 64Mbits SDRAM 20K LUT4, Single Board Computer Support microSD RGB LCD LED JTAG HDMI Port (Not Welded)

Tang Nano 20K is a development board, using the GW2AR-18 QN88 FPGA, containing 20736 LUT4 logic cells and 15552 Flip-Flops. There are 2 PLL in this FPGA chip, and many DSP units supporting 18 bit x 18 bit multiplication. Onboard BL616 is used for downloading bitstream into FPGA, and it's also used as USB to serial convertor to communicate FPGA with computer via UART. The 27MHz crystal generates the clock for HDMI display, onboard MS5351 clock generating chip also provides multiple clocks.
