arduino uno r3 and uno r3 difference

Hello

I am confused with two arduino devices which one to order.

ARDUINO UNO R3- Arduino Uno R3

Uno R3 - Uno R3

In my project i will be using NRF24L01 connected to arduino and pin 3 and 4 as output pins.

can someone please suggest which arduino is the best.

The green one is a real Arduino Uno whereas the blue one is a clone

If you want to fully support the Arduino community then buy the green one, if not then by all means buy the blue one.

Both will do what you say you want but you will, of course, need two Arduinos
