![]() The voltage of operation of the ESP microprocessors is 3.3 V compared to the Arduino operating voltage of 5V. NODEMCU ESP8266 VS ARDUINO UNO OPERATING VOLTAGE The 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 The Power barrel jack an ICSP header and a reset button. Beside ATmega328P it contains other elements such as crystal oscillator serial communication voltage regulator etc. Similarly the Arduino Uno is a microcontroller board based on 8 bit ATmega328P microcontroller. NODEMCU is a development board with ESP8266 and a firmware with the same name. Some development boards use basic esp8266 modules and some integrate the chip flash memory and the antenna on the PCB. There are different modules and development boards with this system. The ESP8266 is a microcontroller with Wi-Fi capability.
