Adafruit Feather RP2040 with RFM95 LoRa Radio - 915MHz - RadioFruit and STEMMA QT

The Adafruit Feather RP2040 RF95 LoRa Radio is a powerful development board featuring the RP2040 microcontroller paired with a 900MHz LoRa radio module. It’s designed for creating wireless networks with greater range and lower power consumption compared to Bluetooth LE and WiFi. This board is ideal for portable projects where flexibility and power efficiency are essential.

At the heart of the board is the RP2040 chip, a 32-bit dual-core processor running at 133 MHz with 264 KB of RAM and 8 MB of onboard QSPI flash storage, perfect for running LoRa and LoRaWAN stacks. The Feather design is compact, lightweight, and versatile, with support for LiPo batteries and built-in battery charging.

Key Features:

• LoRa 900MHz Radio Module (868/915 MHz) for long-range wireless communication
• RP2040 microcontroller with dual-core 133 MHz performance
• 8 MB SPI Flash for code and file storage
• 21 GPIO Pins with various peripherals (I2C, SPI, UART, PWM)
• Integrated 200mA LiPo Charger for portable projects
• STEMMA QT Connector for quick and easy integration with I2C devices
• USB Type C Connector for easy programming and debugging
• RFM9x Radio Module for packet radio, supporting transmission over long distances (up to 2 km line-of-sight)
• Onboard RGB NeoPixel for status indication
• 4 Mounting Holes for secure attachment
• Power Options: Runs on USB power or LiPo battery (not included)

Radio Specifications:

• SX127x LoRa module with SPI interface
• Power Output: +5 to +20 dBm (up to 100 mW) selectable in software
• Low Power: ~300uA during full sleep, ~120mA during transmit
• Range: Over 1.2 miles (2 km) line-of-sight with wire antennas, up to 20 km with tuning and directional antennas
• Antenna Options: Use solderable wire antenna or uFL connector for external antennas

Dimensions:

• Board Size: 2.0" x 0.9" x 0.28" (50.8mm x 22.8mm x 7mm)
• Weight: 6.3 grams

The Feather RP2040 LoRa Radio is fully assembled, tested, and includes headers for easy integration with a solderless breadboard. For antenna, you can solder a simple wire or use a uFL connector with an external antenna (not included). A LiPo battery and USB cable are not included but are available separately.

This versatile board is perfect for wireless sensor networks, long-range data transmission, and portable IoT projects.
