Adafruit Feather 32u4 RFM69HCW Packet Radio - 868 or 915 MHz - RadioFruit Air quality for Raspberry PI and Pubkey controllerThe Adafruit Feather 32u4 RFM69HCW Packet Radio is a versatile development board combining an ATmega32u4 microcontroller and a 900 MHz radio transceiver module. Known as a RadioFruit, this board is great for creating wireless networks with longer range and lower power consumption than 2. 4GHz solutions such as Bluetooth or WiFi. This board supports both 868 MHz and 915 MHz frequencies, dynamically tunable via software. It's part of the Feather family,
