The direct use of Arduino IDE development, the same operation with Arduino UNO.Onboard 5V 1A Switching Power Supply (highest input voltage 24V).Arduino compatible, using Arduino IDE to program.These boards take care of that and break out the pins to the ubiquitous Arduino UNO pattern so that you can use DuPont cables directly and can even use some UNO shields (provided that the shield is compatible with the pin layout, voltage, etc). It requires you to figure out how to supply 3.3V and more before you can work with them. Typical ESP8266 ESP-12 boards do not have a convenient power or programming connection. The ESP8266 is an extremely popular microcontroller similar to Arduino with built-in WiFi. the board can be connected using a Micro-B type USB cable.
It consists of 11 digital I/O pins and 1 analog (input) pin. 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. Power The Arduino Uno Wi-Fi can be powered via the USB connection or with an external power supply. If you are starting out with Arduino, or starting with IoT, this is the board to get. The board is controlled by the ESP8266 chip (a 32-Bit processor) and has a larger flash memory compared to an Arduino Uno. The board is based on the ATmega328P with an ESP8266 Wi-Fi Module integrated (datasheet). The Arduino UNO WiFi board is based on the ATmega328 and it has an integrated ESP8266 WiFi Module. This board is compatible with the Arduino IDE and with NodeMCU. The UNO Based ESP8266 Nodemcu Development Board in the form of the Arduino UNO board format. The Wemos D1 R2 Version 2.1.0 is a WiFi capable dev board featuring the ESP8266EX as the controller and WiFi capable device.
