To build this project you'll need the following hardware:

  • Raspberry Pi computer. Most any model will do. This project uses the GPIO header and one USB-A port…so anything but Compute Module or headerless Zero units can work.
  • RTL-SDR software radio USB dongle
  • 3.5" PiTFT display
    • The software is designed to run on a 480x320 3.5" PiTFT display. If you want to get your hands dirty in the code it should be possible to port it to smaller displays like the 320x240 2.8" PiTFT by changing font sizes and other dimensions. But as-is, use the larger 480x320 screen.
    • Many users have reported success using the official 7" Raspberry Pi Touch Display instead of the PiTFT. We’ll provide alternate steps to try.

You might also consider some extra parts to extend the project:
