Tang Nano 20K is a new development board in the Tang Nano series, with the same number of logical units as the Tang Primer 20K, but compressed to an extreme size of 5.5 x2.3cm!It has built-in 64Mbits SDRAM with low latency, making it easier to run the simulator and better to run the soft core Linux system.The download chip on board has been upgraded to the USB2.0 interface, with functions such as high-speed JTAG download, serial communication, high-speed SPI reception, and precise clock configuration~Compared with common FPGA development environments on the market, the IDE installation package required for Tang Nano 20K is only less than 200MB in size; The space occupied after installation is close to 500MB, greatly saving hard disk space. The IDE usage process is extremely streamlined, and beginners will not be overwhelmed by too many .Compared to other IDEs on the market, the IDE used by Tang Nano 20k can provide a pleasant experience of programming in five minutes and synthesizing in just ten seconds.
