WeMos ESP8266 D1 R2 V2.1.0 WiFi Development Board

This is a WeMos ESP8266 D1 R2 V2.1.0 WiFi Development Board. It is a WiFi-enabled board that uses the Arduino layout and operates at 3.3V.
The board has an ESP8266 chip, which is a 32-bit processor with a larger flash memory than an Arduino Uno. It has 11 digital I/O pins and one analog input pin. You can connect the board with a Micro-B type USB cable.
The D1 R2 is compatible with the Arduino IDE and NodeMCU, which are development platforms for the ESP8266EX chip. The board also has an onboard switching power supply that allows you to power it from a source up to 12V..

The board is controlled by the ESP8266 chip (a 32-Bit processor) and has a larger flash memory compared to an Arduino Uno. It consists of 11 digital I/O pins and 1 analog (input) pin. the board can be connected using a Micro-B type USB cable.

The ESP8266 is an extremely popular microcontroller similar to Arduino with built-in WiFi. Typical ESP8266 ESP-12 boards do not have a convenient power or programming connection. It requires you to figure out how to supply 3.3V and more before you can work with them.

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.).

Features:

• Based on ESP-8266EX.
• Arduino compatible, using Arduino IDE to program.
• Support OTA wireless upload.
• Onboard 5V 1A Switching Power Supply (highest input voltage 24V).
• The direct use of Arduino IDE development, the same operation with Arduino UNO.

Package Includes:

• 1 x WeMos ESP8266 D1 R2 V2.1.0 WiFi Development Board
