Description :

The 868MHz antenna needs to be in connection with the IPEX interface (if the antenna is not connected, the signal reception will be unstable)
Lithium battery charge and discharge circuit, when the battery is full, the blue LED will stop working. When using, please 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!
 

Specifications:

This product is a SX1276 chip based on ESP32 WIFI including OLED, namely LoRa remote modem, 868MHz frequency, high sensitivity is over-148dBm, + 20dBm output power, high reliability, long transmission distance.
