Adafruit Feather M0 RFM96 LoRa Radio - 433MHz

The Adafruit Feather M0 with LoRa 433 MHz combines a powerful ARM Cortex-M0 microcontroller with a long-range LoRa radio in a compact Feather form factor. It is built around the ATSAMD21G18, a 32-bit microcontroller running at 48 MHz with 256 kB of Flash and 32 kB of RAM. This provides plenty of processing power and memory for applications such as IoT networks, wireless data logging, and sensor-based projects.

The integrated RFM96 LoRa module enables long-range communication with very low power consumption, making it ideal for reliable wireless connections over extended distances. An onboard LiPo battery charger allows the board to run from either USB or a 3.7 V LiPo battery, with automatic switching between power sources. As part of the Feather ecosystem, it is compatible with a wide range of add-ons and accessories for fast and flexible development.
