Adafruit Feather M0 900MHz RFM69HCW Packet Radio

Adafruit Feather M0 RFM69HCW Packet Radio is offered as a microcontroller with an RFM69HCW packet radio transceiver. The Feather M0 RFM69HCW Packet Radio features a built-in USB and battery charging. The packet radio also integrates an Adafruit Feather M0 in a 900MHz radio module. Designers can use this 900MHz radio version for either 868MHz or 915MHz transmission and reception.

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.

The Feather M0 RFM69HCW Packet Radio supports portable projects. The development board does this by including a connector for Adafruit 3.7V lithium polymer batteries and built-in battery charging.
