OTA WeMos D1 CH340 WiFi Development Board ESP8266 ESP-12E

Description:

The OTA WeMos D1 CH340 WiFi Development Board ESP8266 ESP-12E is a more Powerful Arduino with WIFI support.This development platform Espressif based on the ESP-8266 is the pins of the Arduino Uno almost compatible and can even be used as some shield modules designed for the classic Arduino Uno.

Features

• Integrated 5V 1A switching power supply (maximum voltage 24V)
• Based on ESP-8266EX
• Arduino compatible, using IDE Arduino to program
• 11 x I/O x pin
• 1 x ADC x pin (input range 0-3.3V)
• Support OTA wireless upload
• Parameters:CPU 80 Mhz,Speed of 115200
• You need setup CH340G(USB to UART IC) driver,if you first use it.

How to get started with OTA WeMos D1 WiFi development board

WeMos-D1R2 is an ESP8266-12 based WiFi enabled microprocessor unit on a Arduino-UNO footprint. That means the board looks and works (in most cases) like an UNO. Apparently several shields, sensors and output devices that are manufactured for the Arduino platform will work on the WeMos-D1R2 with the added advantage of builtin WiFi.

Differences Between the I/O Pins.

Though the Arduino UNO and the WeMos-D1R2 are similar, there are a few differences in their pin assignment. The above illustration provides the mapping of the pins. In some situations programs written for the UNO will need to be modified a little to the proper pin assignments of the WeMos-D1R2. More on this when we write our first sketch.
