Adafruit METRO 328 without Headers

Adafruit METRO 328 without HeadersWe sure love the ATmega328 here at Adafruit, and we use them 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 Metro Mini, but when size isn't as much of a concern, and a USB serial converter is required, we reach for an Adafruit METRO. METRO is the culmination of years of playing with AVRs: we wanted to

The LEDs are 'chainable' by connecting the output of one Jewel into the input of another
