WeMos D1 ESP-12 USB Mini Lite WIFI ESP8266

This new board is based on the ESP8285, an ESP8266 spinoff chip that was designed for use in wearables. The main benefits of the ESP8285 are the integrated 1MByte flash and the resulting incredibly small size. The specifications of the ESP8285 otherwise seem to match the ESP8266. Additionally, the new Wemos Mini Lite has the same form factor as the other Wemos Mini models.

• 11 digital input/output pins, all pins have interrupt/pwm/I2C/one-wire supported(except D0)
