That is because the Arduino part frees the FleaFPGA Uno from the breadboard: you can easily program, control and interface with the FPGA over a serial line or a wireless link using the Arduino IDE.

The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino ...
