This is the Adafruit Feather M0 RFM69 Packet Radio (868 or 915 MHz) - our take on an microcontroller with a RFM69HCW packet radio transceiver plus built in USB and battery charging. Its an Adafruit Feather M0 with a 900MHz radio module cooked in!
The ATSAMD21G18 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.
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.
ISM band Radio Features:
SX1231 based module with SPI interface
Packet radio with ready-to-go Arduino libraries
+13 to +20 dBm up to 100 mW Power Output
50mA (+13 dBm) to 150mA (+20dBm) current draw for transmissions
Range of approx. 350 meters, depending on obstructions, frequency, antenna and power output
Create multipoint networks with individual node addresses
Encrypted packet engine with AES-128
Simple wire antenna or spot for uFL connector
Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE. We also toss in some headers so you can solder it in and plug into a solderless breadboard. You will need to cut and solder on a small piece of wire (any solid or stranded core is fine) in order to create your antenna. Lipoly battery and USB cable not included
