WEMOS D1 mini ESP8266-12F

WEMOS D1 mini ESP8266-12F is a board with soldered ESP8266-12F. It has a built-in USB-UART converter (CH340), thanks to which we can program the board via USB without an additional converter. We have 9 GPIO ports available that support PWM, I2C, SPI and 1-Wire. The board has a 3.3V voltage regulator, so the module can be powered from a USB port, e.g. using a charger with a microUSB connector.
