UNO R3 Arduino-compatible board with the ATMega328P, ATMega16U2 and CH340G serial converter

Since Arduino is an "Open Source" hardware as well as software; anyone can duplicate the Arduino Uno R3 boards exactly, even using original parts, this means we are able to supply this Arduino compatible board at a fraction of the cost of the original but still working identicaly to the original.

The UNO is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with. The UNO is the most used and documented board of the whole Arduino family.
