Adafruit METRO is a derivative of the Arduino UNO board (RS 769-7409) so you can find plenty of projects and example code to use and adapt. Running the ATmega328P at 16 MHz with 32 KB of flash and 2 KB of RAM it is perfect for most simple projects. There are 19 GPIO pins including analogue inputs, hardware UART, SPI and I²C, timers and PWM. Logic level is 5 V but it can easily be converted it to 3.3 V.
Headers are assembled and soldered on for you and the board is fully tested.
