This is a LEGO minifigure sized development board using an Atmel SAMD21E M0 chip. I basically followed the recommended layout/setup from the SAMD21 spec sheets.

R3 may or may not be needed during programming.

SDA/SCL lines have 4.7k pull-up resistors

Included a 3.5mm WS2812B LED for fun.

Latest version removes the 0.8mm 8 pin connector that I really wanted to use because of the very low profile. Instead I went to a 10-pin 1.27mm pitch SMT connector. Should be easy to find - they are the same as Cortex Programming/Debugging connectors. Makes for a high profile backpack for MINI SAM, but oh so much easier to solder.
