Seeeduino V3 (Atmega 328P)

Price: $22.50
Availibility: In Stock
Item #: SS-ARD128D2P

Option 1:

Seeeduino v3.0 328P is an Arduino-compatible board. Its design is based on Duemilanove scheme, 100% compatible to existing programs, shields and IDEs. On the hardware however, many changes have been made to improve the flexibility and user experience.

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. 

Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino projects can be stand-alone or they can communicate with software on running on a computer (e.g. Flash, Processing, MaxMSP). 


  • Inherits all of Arduino Duemilanove's features.
  • Compatible to Diecimila's pin layout, screw hole, and dimensions.
  • Evolved with SMD components
  • Improved on extensibility and convenience.
  • Flat DC Jack
