The Uno R3 CP2102 ATmega328P Development Board is the low-cost version of the popular UNO R3 Arduino. Instead of ATmega16U2 processor, it is assembled with CP2102 IC. UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a 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.
