add PID for ECCN M0

[bradanlane]

The Bradán Lane STUDIO has created a small PCB using the SAMD21G18 with 4MB of extra flash memory (intended for application data or for CircuitPython code and libraries). It also contains touch pads, a buzzer, and LEDs.

The design is suitable for created a macropad or a small game.

This pull request is to provide a PID for the ECCN M0 for both C/C++ programming and CircuitPython.

Please link to the software that this will run and use the PID. (For example, your branch of CircuitPython that adds support.)

Hardware files are Kicad and fine.

The

How do I include a "source" url for the hardware design plus a "source" url for the CircuitPython firmware as there is only a single field?

The branch for CircuitPython is:

https://github.com/bradanlane/circuitpython/tree/bls_coin_m0

In an attempt to comply, I changed the "site" url to be the hardware design and set the "source" to be the CircuitPython branch.

A CircuitPython PR merge is pending review.

The board is now in the CircuitPython build.

sorry for the typos in the code change commit comment

How do I include a "source" url for the hardware design plus a "source" url for the CircuitPython firmware as there is only a single field?

I think folks generally link to the hardware repo and the README in the hardware repo links to the software repo.

CP source ok.
