Description: Tang Nano20K is a development board in the for Tang Nano series, with the same number of logical units as Tang Primer20K, but with a volume compressed to the extreme of 5.5X2.3cm! It is equipped with low latency 64 Mbits SDRAM, making it easier to run emulators and better for running soft core Linux systems. The onboard download chip has been upgraded to the USB2.0 interface, which has the functions of high-speed TAG download, serial communication, high-speed SPI reception, and precise clock configuration Compared to the previous Nano series FPGA chips, it is a huge upgrade. Maker design? Reto game console? DY development? Learning Verilog? RISC-V Soft Core? It can satisfy you. Note: Due to different batches, there may be differences in product appearance and printed text, which does not affect use.
