This product is a SX1276 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 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, pay attention to the positive and negative of the battery, otherwise it will be daed!
With IO port Press sn Press signal input, you need to add the 100nF pull-down capacitor to this pin.
the onboard 4Mt bytes (32 Mt bit) wi-fi antenna,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.
