This WeMos D1 R2 development board for Arduino / NodeMCU is a WiFi capable ESP8266 based development board in the format of the Arduino UNO R3. This board is compatible with the Arduino IDE and with NodeMCU.
The D1 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 a 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 peripherals to the I/O pins, because this is a 3.3V logic level device and higher levels on any pin could damage it. The maximum input voltage for the analog pin is 3.2V.
