![]() So this may be an issue for purchasers who do not already have their own Raspberry Pi. One problem is that we note that most Raspberry Pi resellers are out of stock and the component supply crisis appears to have slowed Raspberry Pi production. Although it should be possible to use the Raspberry Pi as a host device if you wanted to use the SDR on a PC. This is a very fast interface allowing the IQ samples to stream back and forth, however the disadvantage is that the CaribouLite will only work on Raspberry Pi devices. Instead they make use of the SMI (Secondary Memory Interface) connector, which is a high bandwidth interface available on Raspberry Pi's. One interesting design feature is that the CaribouLite does not interface with the Raspberry Pi via USB or Ethernet which is how most SDRs interface. The libcariboulite drivers support Soapy API, meaning that many SDR programs including SDR++, GQRX, CubicSDR and GNU Radio will be able to support the CaribouLite. The unit is capable of up to 14 dBm of transmit power. Both channels use a 13-bit ADC, capable of a bandwidth of up to 2.5 MHz maximum. The full version comes with two TX/RX half-duplex channels, with channel one covering 30 MHz to 6 GHz, and channel two covering sub 1 GHz only. However, certain projects may want to make use of the ISM band only version as they note that it may easier to obtain regulation compliance. For most people the full version will be most desirable as it covers the full 30 MHz - 6 GHz range. It comes in two versions, the full and ISM band only versions. ![]() The CaribouLite is entirely open source and designed for makers, hackers, educators, and researchers. CaribouLite turns your Raspberry Pi single-board computer (SBC) into a self-contained, dual-channel radio Tx/Rx that spans a wide tunable frequency spectrum up to 6 GHz. CaribouLabs write:ĬaribouLite is an affordable, open-source, dual-channel software-defined radio (SDR) platform-and an SDR-focused FPGA development framework-implemented as a Raspberry Pi (RPi) HAT. The product is expected to ship in May 2022. The project has just launched on Crowd Supply with a price tag of $119 for the CaribouLite, and $69 for a CaribouLite ISM only band version.
