ATmega32u4 Leonardo Development Board

The Arduino-compatible VMA103 is a microcontroller board based on the ATmega32u4 and is pin compatible with Arduino Leonardo boards. It has 20 digital input/output pins (7 of which can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller, so all you need to do is connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
