ESP8266 WeMos D1 R2 is a Arduino and Arduino IDE compatible, 32 bit, 4MB flash, 80MHz, for Internet Of Things, web server.
The version D1 R2 V2.1.0 is the latest model of the WeMos D1 series, and is equipped with a newer, more stable Wifi module.

This very popular 2.4GHz Wifi module (802.11b/g/n) is almost 10 times faster than an Arduino Uno, and comes with plenty of memory. After installing the board file, the Arduino IDE can be used to develop and upload programs to the Wifi module. The header can be used to attach other Arduino shields. The on-board switching power supply can operate on input voltages upt to 24VDC.

Attention: This is a 3.3V logic level device!

The D1 R2 is a WiFi capable ESP8266 based development board in the form of the Arduino UNO board format. This board is compatible with the Arduino IDE and with NodeMCU. The D1 also features an on-board switching power supply which allows you to power the board from a power supply up to 24V, 11 GPIO pins (can be used as input/output/PWM/I²C, except D0), and 1 analog input. The PWM resolution is 10bit (1MHz frequency). The integrated 5V switching power supply (1A) is followed by an 3.3V LDO to supply power for the Wifi module and the 3.3V output (power supply for sensors and shields). Please pay attention when you connect other active periphery to the I/O pins, because this is a 3.3V logic level device and higher levels on any pin will destroy it. The max. input voltage for the analog pin is 3.2V.
