With the second version being pretty much where I wanted it, I decided to go ahead, publish all the designs and code, and once I had done that, apply for the open source hardware certification.

The PewPew LCD is now officially certified open source hardware, with number CH000013.

I also submitted a pull request to include the board definition in CircuitPython, but before that, I had to apply for USB VID/PID numbers.

Once that is merged, I will need to add the board to circuitpython.org.
