Datasheet

Plug your Metro M0 into your computer using a known-

good USB cable.

A lot of people end up using charge-only USB cables

and it is very frustrating! So make sure you have a USB

cable you know is good for data sync.

Double-click the Reset button next to the USB

connector on your board, and you will see the NeoPixel

RGB LED turn green. If it turns red, check the USB cable,

try another USB port, etc.

If double-clicking doesn't work the first time, try again.

Sometimes it can take a few tries to get the rhythm right!

You will see a new disk drive appear called

METROBOOT.
