Adafruit Feather M0 433MHz RFM69HCW Packet Radio

Adafruit Feather M0 433MHz RFM69HCW Packet Radio is a microcontroller with an RFM69HCW packet radio transceiver. The packet radio features built-in USB and battery charging. The device also integrates Adafruit Feather M0 in a 433MHz radio module.

The design is based on 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. To support portable projects, the development board includes a connector for Adafruit 3.7V lithium polymer batteries and built-in battery charging.
