D1 R2 WiFi ESP8266 wifi board
Wemos D1 R2 WiFi microcontroller using ESP8266 WiFi communication module. Can be configured via the Arduino IDE and nodemcu management interfaces. Almost all microcontroller connectors support interrupt, PWM, I2C and one-wire functions. It also differs from the UNO in much larger memory (even 4 Mb) and operating frequency (up to 160 MHz), but its size is the same.
Technical data:
- 11 digital input/output pins, all pins have interrupt/pwm/I2C/one-wire supported(except for D0)
- 1 analog input(3.2V max input)
- Micro USB connection
- Power jack, 9-24V power input.
- Compatible with Arduino
- Compatible with nodemcu
