Adafruit Feather RP2040 RFM69 Packet Radio - 868 or 915MHz

The Feather RP2040 RFM69 Packet Radio (868/915 MHz) combines the RP2040 dual-core processor with an SX1231-based RFM69HCW radio transceiver for wireless data communication. The exact frequency is software-configurable for 868 MHz or 915 MHz ISM bands. It includes a STEMMA QT connector and a uFL connector for attaching larger external antennas.

The RFM69HCW radio handles small data packets with up to 100 mW output power, AES-128 encryption, and multipoint networking. With the RP2040's dual cores and 264 KB RAM, you can process radio data on one core while running your main application on the other. Ready-to-go libraries are available for both Arduino and CircuitPython.
