Tang Nano20K is a new development board in the Tang Nano series, featuring the same number of logic units as the Tang Primer20K, with a compact size of 5.5 x 2.3 cm. It includes low-latency 64 Mbit SDRAM, supporting emulator applications and soft-core Linux systems. The onboard download chip has been upgraded to a USB 2.0 interface, enabling high-speed configuration download, serial communication, high-speed SPI reception, and precise clock control. This represents a significant upgrade over previous Nano series FPGA chips. Ideal for makers, retro gaming projects, DIY development, learning Verilog, and RISC-V soft-core implementations. Note: Product appearance and printed text may vary slightly between batches, which does not affect functionality.
