<br>[[File:图片1-0548A.png|500px|frameless|thumb]]<br> 

== Description ==

Doing experiment with electronic products, we often program on the Arduino IDE development environment with Arduino series microcontrollers. <br>
Keyestudio Uno PLUS control board is fully compatible with Arduino IDE development environment. It is as same as the Arduino UNO R3 board. Moreover, some improvements we made highly strengthen its function(as shown below). In order to wire efficiently, we equip with a 1m USB cable with type-c interface for you. <br>
