This is the Adafruit Feather 32u4 Radio (RFM69HCW) 900MHz - our take on an microcontroller packet radio transceiver with built in USB and battery charging. Its an Adafruit Feather 32u4 with a 900 MHz radio module cooked in! Great for making wireless networks that can go further than 2.4GHz 802.15.4...# Author: Tony DiCola import board import busio import digitalio import adafruit_rfm69 # Define radio parameters. RADIO_FREQ_MHZ = 915.0 # Frequency of the radio in Mhz. Must match your # module! Can be a value like 915.0, 433.0, etc. # Define pins connected to the chip, use these if wiring up the breakout according to the guide: CS = digitalio .
The RFM69HCW is an inexpensive and versatile radio module. You can use it to send text or binary data between two or hundreds of modules. It's perfect for building inexpensive short-range wireless networks for home automation, citizen science, and more.
