Description
The 433MHz antenna must be used in conjunction with the IPEX interface (if the antenna is not connected, it may damage the LoRa chip)
Lithium battery charging and discharging 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!
Using the IO port touch screen touch signal input, you need to add the 100nF pull-down capacitor at this pin!
Example
This product is a SX1278 chip based on ESP32 WIFI increased OLED, namely LoRa remote modem, 433MHz frequency,
