The TTGO LoRa32 SX1276 – 868/915MHz OLED is an ESP32 development board with a built-in LoRa chip and an SSD1306 0.96 inch OLED display. In this guide, we’ll show you how to: send and receive LoRa packets (point to point communication) and use the OLED display with Arduino IDE.
SX1276 chip based on ESP32 Wi-Fi, 868 – 915 MHz frequency, high sensitivity over -148 dBm, + 20 dBm output power, high reliability, long-transmission distance. Onboard 32 MB flash Wi-Fi antenna, 0.96-inch OLED display, lithium battery charging circuit, 9102X interface and USB serial chip, support for Arduino development environment perfectly, can be used for program checking, product development is very easy and fast.
