ATmega328 Uno Development Board

The VMA100 is an Arduino Uno compatible microcontroller board based on the ATmega328. It has 14 digital input/output pins (6 of which can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, USB Type-B socket, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller, just connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. (USB cable and power adapter sold separately).
