The Adafruit Feather RP2040 RFM69 Packet Radio features a compact design that seamlessly combines a microcontroller with a high-power 868/915 MHz radio module. With its RP2040 chip running at 133 MHz and 3.3V logic, it offers robust performance and portability for creating versatile wireless networks.
Specifications include 8MB of QSPI FLASH, 264KB of RAM, and a plethora of GPIO options: 21 pins, including 4 ADCs, 2 I2C, 2 SPI, and 2 UART interfaces, plus 16 PWM outputs. Integrated 200mA+ Lithium polymer charger and USB Type C power/data support ensure seamless power management.
Ideal for wireless sensor nodes or packet radio projects, its RFM69 module allows 500m range with the possibility of longer distances using directional antennas. Capable of transmitting encrypted data packets via the license-free ISM band, it includes features like ready-to-go Arduino & CircuitPython libraries.
The board supports flexible antenna options with both solder pads and a uFL connector, offering potential for extensive customization. Easily create multipoint networks thanks to its embedded AES-128 encryption and individual node addressing capabilities.
Versatile, lightweight (6 grams), and measuring just 52.2mm x 23.0mm x 7.3mm, it serves perfectly for projects demanding low power consumption and wireless communication, providing superior range over 2.4 GHz technologies while being simple to integrate.
