Discharge pin

Description: The 433/470MHz 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 SX1278(433/470)chip based on ESP32 WIFI increased OLED, namely LoRa remote modem, 433/470MHz frequency, high sensitivity is over-148dBm, + 20dBm output power, high reliability, long transmission distance. the onboard 433 MHz 16 Mt bytes (128 Mt 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.
