Use the 3V one to interface with sensors and devices that need 3V logic, or when you want to power it off of a LiPo battery. The 3V version should only run at 8 MHz. Use the 5V one for sensors and components that can use or require 5V logic.

Instead of the ATmega328, this Metro features a ATSAMD21G18 chip, an ARM Cortex M0+. It's our first Metro that is designed for use with CircuitPython!
