Arduino Uno R3 Boost Step-up Power Module DC 3V-6V to 1000KV with protect circuits SMALL SIZE and extremely fast responseIntroduction : Arduino Uno R3 is a microcontroller board based on a removable, dual inline package (DIP) ATmega328 AVR microcontroller. It has 20 digital input output pins (of which 6 can be used as PWM outputs and 6 can be used as analog inputs). Programs can be loaded on to it from the easy to use Arduino computer program. The Arduino has an extensive support community, which makes it a very easy way to get started working with embedded electronics.
