About CaribouLite

CaribouLite is a Raspberry Pi HAT that turns 40-pin Raspberry Pi boards into a transmit and receive 6 GHz software-defined radio. The repository contains driver, firmware, hardware, software and examples for a dual-channel, standalone radio platform intended for makers, hackers and researchers.

It mounts on an unpowered 40-pin board and is installed by cloning the repository and running install.sh with an internet connection. It does not support Raspberry Pi 5 because of the missing SMI interface, and installation requires kernel headers, password entry, and disabled SPI and ARM I2C overlays.

Key features

  • Transmit and receive SDR operation up to 6 GHz on Raspberry Pi
  • 40-pin Raspberry Pi HAT form factor, including RPI-Zero mounting example
  • Dual-channel standalone software-defined radio hardware design
  • SoapySDR and SoapyRemote API tools build and installation
  • SMI stream kernel module with IIR DSP library and utilities
  • Install script verifies Raspberry Pi boot configuration for compatibility
Best for: Makers, hackers, and researchers experimenting with SDR on 40-pin Raspberry Pi boards.
Good for

CaribouLite FAQ

Does CaribouLite work on Raspberry Pi 5?
No. The source states it is not supported on Raspberry Pi 5 due to architectural changes and removal of the SMI interface.
How is CaribouLite installed?
Mount it on an unpowered 40-pin Pi, boot the Pi, clone the repository, and run install.sh with an internet connection. You will be asked to enter your password during installation.
Do I need to change Raspberry Pi settings?
Yes. The SPI and ARM I2C overlays should be disabled, and the installer only checks /boot/config.txt and warns about problems, so you must adjust the parameters yourself.
Is something wrong or out of date?
