WIFI D1 MINI ESP8266 dev. board, 32Mbit flash, USB CP2104
The set includes:
WiFi D1 mini PRO is an integrated ESP8266-based WiFi-enabled microprocessor unit equipped with 32Mb (megabits) of flash memory. It is pin-compatible with the WeMos D1 mini / mini PRO boards.
WiFi D1 mini PRO comes with an embedded CERAMIC WiFi antenna on-board, and has a connector for an optional external antenna.
The input power can vary from 4 to 9V DC (supplied to the «5V» pin). We recommend to supply exactly 5V in case of using external shields requiring 5V operation. The unit can also be powered directly from the USB port. Alternatively, you can power the WiFi D1 mini PRO from a stabilized 3.3V source by connecting it to the «3.3V» pin on the PCB.
PC communication is done via CP2104 (USB-TTL). Corresponding driver may need to be installed on your system. In order to use WiFi D1 mini PRO with an Arduino IDE, please use the ESP8266 library.
