LoRa Gateway - LoRa module with WiFi/BT ESP32-WROOM-32E and RFM95W

Description

LoRa module based on ESP32-WROOM-32E with WiFi and Bluetooth communication and LoRa RFM95W modem. The board has ESP32 pins and a Qwiic connector that allows you to connect additional sensors. RFM95W works in the 868 MHz or 915 MHz band and can work as a gateway or LoRa device. For the proper operation of the board, an antenna is required, which can be connected via the u.FL connector (recommended for greater ranges) or connecting the antenna in the form of a cable with a length of approx. 7.5 cm to the pin. The board is powered and programmed via the microUSB connector. One of the ideal uses of the module is to convert LoRa (long range) radio messages into data packets that can be accessed via the Internet. It is perfect for monitoring several LoRa devices and transferring their messages to the cloud. Full documentation with the Arduino library and examples of use is available on the product page.
