Adafruit Feather M0 RFM69 Packet Radio Now Available

Adafruit Feather M0 RFM69 Packet Radio

Adafruit has today announced a new addition to their ever-growing range of Feather development boards and accessories with the launch of the new Adafruit Feather M0 RFM69 Packet Radio.

The new board has been designed by Adafruit to provide users with their take on the micro-controller with a RFM69 HCW packet radio transceiver plus built in USB and battery charging.

Adafruit explains a little more about what you can expect from their latest Feather hardware which is now available to purchase from the Adafruit online store priced at $24.05 for the 433MHz version with a 900MHz version arriving shortly. Jump over to the store via the link below.

At the Feather M0’s heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic, the same one used in the new Arduino Zero. This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip.

To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don’t need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.
