SAMD21E based Minifigure shaped development board.

Hello World 👋

I'm currently working on fun things and you can find me on Mastodon. If you got here looking for Mini SAM development boards, the repository is below OR you can order pre-made boards directly from Mini Fig Boards.

minifigure-samd21e's Issues

64kb

We're you able to get circuitpython on 64kb? What's the smallest you think you need? They sell the same package in 32kb and 16kb. I guess I'm also curious why you redesigned this project with the SAMD21G? thanks

Beautiful Work

It's the best thing shared on OSH Park recently. I hope there's a Kickstarter soon. An easy tool chain, like Teensyduino, would make it awesome, but I know it's a lot of work to create and maintain.

One little issue I noticed is the connection of the USB shield to ground. There's endless discussion in forums, with several camps:

1. open circuit
2. parallel RC to ground, typically 4.7nF and 1M
3. 0603 ferrite bead to ground, they're cheap
4. trace to ground

Since most USB Micro-B cables either don't have a shield, or don't connect it on the B side, you'll get away with 4. most times, but apparently it will not pass USB certification. For your application I would go with 1.
