2Pcs LILYGO® TTGO 868MHz SX1276 ESP32 LoRa 0.96 Inch Blue OLED Display bluetooth WIFI Module IOT Development Board

If you need the 915MHz version, please click here to buy: Product ID 1545115 Description: The 868MHz antenna needs to be in connection with the IPEX interface (if the antenna is not connected, it may damage the LoRa chip) Lithium battery charge and discharge circuit, when the battery is full, the blue LED will stop working. When using, pay attention to the positive and negative of the battery, otherwise it will be damaged. With IO port touch screen touch signal input, you need to add the 100nF pull-down capacitor to this pin. Example: The products is a SX1276(868) chip based on ESP32 WIFI increased OLED, namely LoRa remote modem, 868MHz frequency, high sensitivity is over-148dBm, + 20dBm output power, high reliability, long transmission distance. the onboard 868MHz 4Mb bytes (32 Mb bit)wi-fi antenna, 0.96 inch blue oled display, lithium battery charging circuit, CP2102 interface and USB serial chip, the perfect support for Arduino development environment, can be used for program checking and product development is very easy and fast.
