Frequently Asked Questions:
Q1. Why are these called " Compatible"?
A1. The group demanded us to remove their logos and rename these products so that they do not lead customers to believe they are the same units sold by Arduino
Q2. Are these 100% compatible with the "normal" ?
A2. Yes, they really are completely compatible with "normal". Build quality looks the same and everything (studio, library, tools, etc) just works

    It's an Arduino
    High quality, low cost, great opportunity to build and learn. Man we live in a great time don't we? Tools like this will always get 5+ stars from me. The Arduino has great community support. There are excellent projects, shields and sketches available and learning to build/write your own is easily achievable.

    Please... if you are looking for a new hobby consider the Arduino or Parallax microcontrollers. Both are excellent not just for starting out but for some really complex stuff. The Arduino is open source and has excellent community support. It's a wonderful time for hobbiests!
    Specifically bought this on Gearbest for the price here was lower than anywhere else I looked when I purchased, so no complaints there.

    This is my first microcontroller (at the time of review) so I can't really compare it's performance to others. I can say that self taught but moderately experienced in electronics and programming this by and far exceeded my expectations. I was up and running the first day and haven't experienced any problems since. The potential of these little boards is huge and I'll be ordering more soon. Be aware that you will need a USB-B to USB-A male-male cable, if you have a printer it probably uses one.

    Perfect Arduino
    Worked with the Pulse Sensor AMPED just like the "original" Arduino would!

    Can run Standard Firmata used for Windows Virtual Shields and Remote Arduino App.

    Easily programmable with the cable provided .

    Perfect quality thanks Gearbest !

    Arduino Uno R3
    Quality of this board is good. Looks like original. Easily could read from any sensors (I tried HC-SR04 sonar). Also is suitable as ATtiny85 programmer.
    Price is little bit high
