Uno R3 ATMEGA328 CH340 Development Board

$2.09 – $2.23

Arduino Uno R3 is a microcontroller board based on the ATmega328P. It features 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. Due to the low-cost, you can tinker with your UNO without worrying too much about doing something wrong.
