Adafruit Feather M0 900MHz RFM95 LoRa Radio
Adafruit Feather M0 900MHz RFM95 Long Range (LoRa) Radio is a microcontroller with a LoRa packet radio transceiver. The packet radio includes a built-in USB and battery charging. The device also integrates Adafruit Feather M0 in a 900MHz radio module. Designers can use this 900MHz frequency module version for either 868MHz or 915MHz transmission and reception.
The RFM95 900MHz LoRa Radio supports wireless networks that are more flexible than BLUETOOTH® LE. In addition, the device does not have the high-power requirements of WiFi. The Feather M0 with RFM95 900MHz LoRa Radio operates using the ATSAMD21G18 ARM Cortex M0 processor, which is clocked at 48MHz and at 3.3V logic. The processor offers 256K of flash and 32K of RAM. The built-in USB provides a USB-to-Serial program and debug capability.
