Adafruit Feather M0 433MHz RFM96 LoRa Radio

Adafruit Feather M0 433MHz RFM96 LoRa Radio is a microcontroller with a Long Range (LoRa) packet radio transceiver. The packet radio includes a built-in USB and battery charging. The device also integrates Adafruit Feather M0 in a 433MHz radio module. The Feather M0 RFM96 433MHz 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 device operates using the ATSAMD21G18 ARM Cortex M0 processor, which is clocked at 48MHz and at 3.3V logic. The chip offers 256K of flash and 32K of RAM. The built-in USB provides a USB-to-Serial program and debug capability. To support portable projects, the Feather Boards include a connector for Adafruit 3.7V lithium polymer batteries and built-in battery charging.
