Adafruit Feather 32u4 RFM96 LoRa Radio - 433MHz - RadioFruit

The Adafruit Feather 32u4 LoRa Radio (RFM9x) is a compact, lightweight development board featuring a microcontroller combined with a long range (LoRa) packet radio transceiver. Operating at 433 MHz, this board supports creating wireless networks that exceed the range of traditional 2.4GHz wireless technologies like Bluetooth LE and WiFi while maintaining low power consumption.

Key features include an ATmega32u4 microcontroller clocked at 8 MHz with 3.3V logic, built-in USB programming and debugging capabilities, and battery charging support for 3.7V Lithium Polymer batteries. The Feather measures 51mm x 23mm x 8mm, weighs only 5.5 grams, and offers 20 GPIO pins including PWM and analog inputs, making it versatile for various projects.

The integrated SX1276 LoRa module enables packet radio communication with up to 100 mW power output, operating on the license-free 433 MHz ISM band. It supports a simple wire antenna or uFL connector for flexible antenna options. The board is ideal for long-range, low power IoT and wireless sensor applications.
