Seeeduino V2.21 (Atmega 328P)

Seeeduino V2.21 has been replaced with newer version Seeeduino V3.0 (Atmega 328p).

Description: Seeeduino is an Arduino compatible board. Design of this Arduino board is based on Diecimila scheme, 100% compatible to its existing program, Arduino shields and IDEs. On the hardware part, remarkable changes are taken to improve the flexibility and user experience. It contains everything needed to support the microcontroller; simply connect it to a computer using a USB cable or power it with a AC-DC Adapter or battery to get started. Seeeduino V328 is fully compatible with Arduino shields designed for the Arduino UNO or Duemilanove, also shares accessories with Seeeduino family.

Note: You need to use DC jack to JST 2pin converter for supplying from AC-DC Adapter or you can connect power supply 7-12V using JST 2pin connector.

This Arduino board can be connected to PC using a miniB USB Cable.
