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. ESP32 VS ARDUINO NANO PINOUT SERIALBeside 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. NODEMCU ESP8266 VS ARDUINO UNO:- In this article, we will be discussing the comparison between ESP8266 and Arduino UNO.

In fact, the two are actually aimed at slightly different directions. ESP32 VS ARDUINO NANO PINOUT CODEIf you need it in the future, you can freely transplant the Arduino code to MCU platforms such as STM32. Generally, you can master the basic features of Arduino in less than a week. Of course, if you have the ability, you can make contact with both. After you get it done, you can take a look at the things made by the Arduino open-source community, and you can easily get it done with STM32. If you have good programming skills, STM32 is recommended. If you are learning just for fun and you are not a major in electronics and have no confidence, Arduino is recommended. If you only study for employment, decisively STM32 microcontroller. If the C skills are weak and come up with STM32, you will soon have the idea of giving up. If you are an ordinary student below the university level who does not have a deep understanding of programming languages, it is recommended to get started with Arduino. In terms of open source: things made with STM32 can be open source if you want to open source, and you can not publish anything if you don’t want open source. However, if you use STM32 development tools such as Keil, it may require hundreds of lines of code or more. For Arduino, it may start from a new project and it can be realized with 10 lines of code. For example, the serial port outputs a simple string. ESP32 VS ARDUINO NANO PINOUT PROFESSIONALSTM32 is mainly used as products for professional developers, which requires certain professional knowledge, but at the same time, it is relatively complicated to write code to realize functions. In fact, there are many simple instruments in the factory, such as temperature controllers, ordinary motor controllers, low-end PLCs, and some civilian toys, game controllers, wired keyboards and mice, and other peripherals and so on are very practical. STM32 pays more attention to engineering practice.
