Here's the story. GOWIN Semiconductor made some low-cost FPGAs. Then Sipeed used them to produce an inexpensive development board. At $5, the Tang Nano FPGA board promises to open the use of FPGAs to a much wider audience interested in much weirder applications, similar to what the ESP8266 chip did for WiFi applications. After all, you'd think twice about doing something crazy with a $100 board, but burning-up a Nano isn't a big deal. One day soon maybe we'll all have Pez dispensers full of Nano boards for building our hardware.
But before we can get there, we need to know how to use the Nano. I don't intend this site as a generic tutorial on what FPGAs are and how to use them: there are already plenty of those. Rather, I'm interested in doing specific projects with the Nano which others can grab and modify for their own uses. As such, I'll create posts describing my experiments and I'll store the design files in the Github repository.
