915MHz TTGO ESP32 LoRa (WIFI+BLUETOOTH+SD CARD+0.96 INCH OLED) DEVELOPMENT BOARD WITH SMA

The ESP32 board has all the functions required for IOT. But these newly introduced TTGO boards are different from the previous Expressif ESP32. These are embedded with the ESP32 chip along with the SX1278 which allows it to work with LoRa technology via SMA connected antenna. This TTGO board also has a 0.96 inch OLED display and SD card slot comes with V2.1 firmware. You can program this board using the Arduino environment. For code please refer to the link below.
