My wafer.space FABulous FPGA is alive! 👏

This chip was part of wafer.space Run 1 (https://github.com/wafer-space/ws-run1), which taped out at the end of last year.

The video below shows the FPGA starting up and pulsing the two onboard RGB LEDs.

It is built using the FABulous (e)FPGA framework and the wafer.space LibreLane template. Everything is 100% open source, down to the silicon. You can find the repository with all the sources here: https://github.com/mole99/gf180mcu-fabulous-fpga

At around 500 LUTs, it's at the lower end of FPGAs. Still, it's capable of a lot, considering that it has 48 I/Os, SRAMs, DSPs, and register files.
