4 layer board of 0.96x1.55 inches (24.36x39.47 mm).

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.

This version has two 2.54mm pitch SMT connectors for a protoboard friendly design.
