Ideal for mobile applications! The board has a connection for 3.7 V Lipo batteries and a charging circuit. The board can be both operated and the battery loaded via the microUSB port. The Feather M0 RFM95 Lora automatically changes from battery to USB operation when the board is connected via USB. The battery voltage can be measured via an analog input of the board. The rest of the Feather 32U4 Lora is taken by an RFM9X Lora 868/915 MHz radio module. The transmission receiver is suitable for the transmission of small data packages over long distances, which are unsuitable for 2.4 GHz networks (BT, BLE, WLAN, ZigBee). The communication between the microcontroller and radio module is via the SPI interface. You can get the right Arduino library for control here: https://www.airspayce.com/mike.
