Development Boards / Metro

The Adafruit METRO is an Arduino Uno equivalent board designed with a few extra features to improve upon the original Uno. We sure love the ATmega328, and we use it a lot for our own projects. The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers, and PWM galore - just enough for most simple projects. When we need to go small, we use a Pro Trinket 3V or 5V, but when size isn't as much of a concern, and a USB-serial converter is required, we reach for an Adafruit METRO.
