- Output: 5V at 1A Max
- Operating Voltage: 3.3V
The D1 R2 is a WiFi capable ESP8266EX based development board in the form of the common Arduino UNO board compatible format. This board is compatible with the Arduino IDE and with NodeMCU. The D1 R2 also features an on-board switching power supply which allows you to power the board from a power supply up to 12V.
WeMos- D1 R2 WiFi ESP8266 Development Board is programmable via Arduino IDE. This is an ESP8266 based WiFi enabled microprocessor unit on a Arduino-UNO footprint. That means the board looks and works (in most cases) like an UNO. 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.
