About

This circuit board was designed as a fun project for a SAMD21E microcontroller based development board. The circuit design follows the recommended design from the SAMD Datasheet - including section 39. Schematic Checklist. The USB protection may be overkill, but it is complete. I made this just for fun - I am not going to provide any special support, but always welcome recommendations, suggestions, and ideas for improvements. You are free to take it and run with it, but do not sell this design.

Etc

I have not yet tested the design. As it sits, it should pass DRC for OSHPark manufacture with two major unknowns. 1) Wether or not the cutouts for the hands will be manufactured as intended and 2) The exact outline of the board - there may be some corners, nooks, and crannies that are not manufactured by OSHPark and will require additional filing/work by me. I will update once I get a set manufactured.

BOM

The schematic has all items listed and values and should be easily sourced. Additionally, I have setup a project on mouser.com that can be found here. The BOM through mouser is roughly 12 USD at this time (Oct 2016). It does not include the WS8212B 3535 LED - these can be sourced from Adafruit or eBay among others. The LED does not need to be populated for the board to function, but it is fun.

Firmware

I plan on trying to implement both Arduino and possibly Micropython on this board, but need some significant help with this. I will update as I can.

Simple demonstration board for various touch pad manufacturing techniques.

It should have four surface touch pads, and 7 side touch pads in two groups of 3 and 4. Group of 4 side touch pads are created with one technique, and the group of 3 side touch pads are created with another.

No real BOM. The top jumper can be a MOLEX 20 pin attached such that one row is on the top and the second row is on the bottom.

NOTE I have not tested this yet and am not 100% sure it will be manufactured correctly.

Shield for Adafruit Trinket that includes a battery charger and WS2812 LED.

This is similar to version A, but is designed to connect to the Trinket “back-to-back” so that the user can still access the reset button and the Trinket front LEDs.
