Our biggest selling microcontroller development board (HCARDU0090). It hast been designed from the open source revision 3 Arduino Uno reference design and comes pre-flashed with the Arduino bootloader. This board is 100% compatible with all shields and modules designed for the Arduno Uno. If you are looking to get into microcontrollers, this is the ideal board to choose. Its very low price together with the freely available Arduino development environment provides a cheap and easy way to get started. We have also designed this board to include a socked microcontroller so that should you accidentally damage it you can simply pop it out and insert a replacement.

Revision 3 of the board has the following new features:

1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin; An IOREF pin that will allow future shields to adapt to the correct IO voltage and second not connected pin that is reserved for future purposes.

Stronger RESET circuit.
Atmega 16U2 replaces the 8U2.
