Whadda WPB100 Atmega328 Development Board

The Whadda WPB100 ATmega328 UNO DEVELOPMENT BOARD (Arduino® Uno compatible) is a microcontroller board based on the ATmega328.

It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; connect it to a computer with a USB cable or power it with an AC to DC adapter or battery to get started.
