An offshoot of the original

This board uses the ATMEL SAMD21E18A

Why this board? The SAMD21E is a tiny little IC that has USB capabilities, making it really simple to incorporate into projects. This board reduces the supporting components to the bare necessities. This makes it super simple to prototype other designs and convert the breakout into a new board.

It features standard 0.1" headers and it fits on a breadboard. All communication pins (TX,RX, I2C, SPI) are broken out. analog input and PWM output pins are also broken out.

A green power LED shows if the device is powered, and a clear blue LED is for user output.

The board provides a reset button, JTAG SWD programming, and a power switch.
