Adafruit Feather RP2040 with RFM95 LoRa Radio - 915MHz

We have ✅ 3 available of the AF-5714 in our Sydney warehouse. An extra 100 units available with a short lead time.

Express post delivery (2-5 business days)

The Feather RP2040 with RFM95 LoRa Radio (915 MHz) combines the RP2040 dual-core processor with an SX1276-based LoRa radio transceiver for long-range wireless communication at 868 or 915 MHz. The frequency is software-configurable for your region's ISM band. LoRa modulation delivers over 2 km range line-of-sight with default settings, and up to 20 km with optimised configurations and directional antennas.

The RP2040's dual cores and 264 KB RAM make it well-suited for running LoRa and LoRaWAN stacks that require significant processing power for packet management. The board includes a STEMMA QT connector and a uFL connector for attaching larger external antennas.

Key Features
