Detail ROBOTDYN WIFI D1 R2 ESP8266 ORIGINAL LIKE WEMOS D1 R2
Wi-Fi D1 R2 is an integrated ESP8266 based Wi-Fi enabled microprocessor unit + 32Mb flash memory on a Arduino-UNO pinout. That means the board looks and works (in most cases) like an UNO. Apparently several shields, sensors and output devices that are manufactured for the Arduino platform will work on the Wi-Fi D1 R2 with the added advantage of builtin Wi-Fi.WI-Fi D1 R2 board using the ArdUINO IDE.For connect to PC need install driver for CH340.On board have embedded Wi-FI antenna and socket for connecting external antenna.
