Metro Mini Notes

A Metro Mini can be purchased here.

Windows and OSX drivers required to communicate with a Metro Mini via USB are here and here.

When using a Metro Mini with the Arduino IDE, use the Arduino/Genuino Uno board setting.

The Metro Mini is powered by an Atmega328 - same as the UNO. So the i2c bus is the same also: SDA is A4 and SCL is A5.
