Adafruit Feather 32u4 RFM96 LoRa Radio - 433MHz

The Adafruit Feather 32u4 LoRa Radio (RFM9x) combines a microcontroller with a Long Range (LoRa) packet radio transceiver for exceptional wireless communication. This board operates at 433 MHz, offering greater range than 2.4GHz networks and more flexibility than Bluetooth LE, without high power demands like WiFi.

At its core is the ATmega32u4, clocked at 8 MHz with 3.3V logic, providing 32K of flash and 2K of RAM. With built-in USB capability, it supports diverse USB functionalities, eliminating the need for additional chips. Its compact design includes a 100mA lithium polymer charger and a power-source switch, effortlessly transitioning between battery and USB power.

The Feather 32u4 LoRa Radio integrates an RFM9x LoRa 433 MHz module, ideal for small data packet transmissions. The SX1276-based module offers up to 100 mW power output, configurable via software. It excels in both amateur and license-free ISM bands, achieving ranges over 1.2 miles (2 km) line-of-sight, with potential for 20 km using directional antennas.

Features include:

• Dimensions: 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm)
• Weight: 5.5 grams
• 20 GPIO pins, 7 PWM pins, 10 analog inputs
• Hardware support for Serial, I2C, SPI
• Embedded USB bootloader compatible with Arduino IDE

Fully assembled and tested, it comes with headers for soldering. A simple wire antenna completes your setup. Enjoy the Feather 32u4's effortless integration into Arduino projects with the ready-to-go libraries, supported by a comprehensive tutorial for setup and usage details.
