What is Radioberry?
Radioberry is an open-source software-defined radio (SDR) transceiver designed as a “hat” add-on for the Raspberry Pi single-board computer. It enables the Raspberry Pi to function as a fully capable HF (high-frequency) SDR transceiver, covering frequencies from 0 to 30 MHz. The project uses the Analog Devices AD9866 chip and an Intel Cyclone 10 LP FPGA, offering both receive (RX) and transmit (TX) capabilities.

How Does Radioberry Work?
Radioberry leverages the processing power and flexibility of the Raspberry Pi, using the Pi as the host for control, user interface, and networking. The HAT handles the RF front-end and digital conversion, while the Pi runs SDR software for operation and visualization. The FPGA is programmed via the Pi, and the radio is controlled through open-source software.
Typical Setup
- Hardware: Raspberry Pi (usually Pi 4), Radioberry HAT, optional touchscreen.
- Software: Raspbian OS, Radioberry firmware, SDR control software.
- Operation: Users can operate the radio locally on the Pi or remotely over a network.
Radioberry with Touch screen
Radioberry version2 features a HF SDR TRANSCEIVER integrated with Raspberry Pi 4B and a 7″ DSI Touch Screen
The product comes as an easy to assemble kit: Raspberry pi 4B 1G + radioberry + 7 inch capacitive touch screen + case + tf card with image flashed, you just need to assemble them together.
