Adafruit Feather RP2040 RFM69 Packet Radio - 868 or 915MHz - RadioFruit and STEMMA QT

The Adafruit Feather RP2040 RFM69 Packet Radio is a compact and powerful development board combining the RP2040 microcontroller with the RFM69HCW 900MHz radio module, ideal for flexible wireless networking beyond Bluetooth LE and lower power than WiFi.

This board is compatible with either 868 MHz or 915 MHz frequency bands depending on software configuration, making it suitable for the European and American ISM bands. It features built-in USB Type C for data and power, along with lipoly battery charging capabilities for portable projects.

Key Features:

• RP2040 dual-core 32-bit Cortex M0+ running at 133 MHz with 264 KB RAM and 8 MB SPI FLASH
• RFM69HCW Packet Radio module supporting 868 or 915 MHz with up to 20 dBm (100 mW) power output
• 21 GPIO pins including 4x 12-bit ADCs, 2x I2C, 2x SPI, 2x UART, and 16 PWM outputs
• Built-in 200mA+ LiPo charger with charging status LED
• Onboard RGB NeoPixel and red status LED
• USB Type C connector for power, data, and bootloader access
• STEMMA QT connector for easy sensor hookups
• Compact size: 52.2 mm x 23.0 mm x 7.3 mm, weighing 6 grams
• Includes headers and requires soldering a simple wire antenna or use an external antenna via uFL connector

Radio Specifications:

• SX1231 based SPI interface radio module
• Power output selectable from +13 dBm to +20 dBm
• Current draw: 50 mA at +13 dBm; 150 mA at +20 dBm; ~30 mA during listening
• Typical range approx. 500 meters line of sight with simple antennas, extended range possible with directional antennas
• Supports encrypted packet communications with AES-128

This Feather combines the flexibility of the RP2040 microcontroller platform with a powerful ISM band packet radio for IoT sensor nodes and wireless projects requiring long range and low power consumption.
