Description
The Arduino Nano Board R3 with CH340 is another popular Arduino development board very much similar to the Arduino UNO They use the same Processor (Atmega328p) and hence they both can share the same program.
Arduino Nano Board R3 with CH340 is a microcontroller board based on 8-bit ATmega328P microcontroller. Along with ATmega328P, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc. to support the microcontroller. Arduino Uno has 14 digital input/output pins (out of which 6 can be used as PWM outputs), 6 analog input pins, a USB connection, A Power barrel jack, an ICSP header and a reset button.
