From the project
Rice ECE BEAMFORM Capstone Project Repo
The OpenPhasedArray is an open-source, modular 4-element transceiver phased-array board adaptable across software-defined radio platforms and optimized for S-band frequencies. It is ideal for hobby or research-grade beamforming experiments or sensing and communications prototyping. It is a modular design that is easily stackable both vertically and horizontally using the provided 3D-printable board mount. It is (optionally) interfaced with by the FT232H USB-to-serial converter for easy, Python-based control.
