Sipeed Lichee Tang Nano minimalist line FPGA development board

Lichee Tang Nano series is Bee simple GW1N-1 FPGA development board based on a high cloud semiconductor design. Compact design delicate boards, chips all resources are drawn onboard Type-C, USB-JTAG, PSRAM, RGB (LCD screen can be accessed, VGA and other peripherals), etc., and all IO resources leads, convenient developer expand the use, ideal for small digital logic design and experiment.

The main features for the Tang Nano FPGA Board include 34 rich I/O PINs and a USB Type-C interface. This allows for the power supply and downloading code. Additionally, the JTAG downloader supports a USB cable, enabling code to be downloaded without an extra downloader outside the board. A 40 Pin FPC LCD carrier allows a 40 PIN RGB LCD Screen to be equipped on the board.
