ATmega328P AVR microcontroller.
We use this in our Peggy 2, Peggy 2LE, Meggy Jr RGB, and Diavalino kits. They're also compatible with our ATmegaxx8 target boards. These chips can be programmed with an Arduino or Arduino Uno bootloader and have 23 programmable I/O in an easy-to-use 28-pin DIP package.
