Product 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, high sensitivity is about -148dBm, +20dBm output power, high reliability, long transmission distance.
The onboard 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 development environment, can be used for program verification and product development is very simple and fast.
Operating voltage:3.3V to 7V
Operating temperature range:-40 degrees C to +90 degrees C
Support for Sniffer, Station, softAP, and Wi-Fi Direct modes
Data rates:150 Mbps@11n HT40, 72 Mbps@11n HT20, 54 Mbps@11g, 11 Mbps@11b
Transmit power:19.5 dBm@11b, 16.5 dBm@11g, 15.5 dBm@11n
Receiver sensitivity up to -98 dBm
UDP sustained throughput of 135 Mbps
