LORA32 868MHZ OLED 1Pair/LORA32 915MHZ OLED 1Pair

Description:
The 868/915MHz 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!
Note:This product does not include the battery.
