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.

Questions
How big is the TX Board Rev2 PCB?
It measures 104.9 × 88.3 mm and has 4 copper layers, 1.57 mm thick.
What parts does the TX Board Rev2 use?
303 parts, built around the PE42423B-Z, MAPS-010164-TR0500, PMA3-63GLN+ and QPA9122TR7. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TX Board Rev2 KiCad files?
From the yilmaz-kaan/OpenPhasedArray repository on GitHub, at the commit this page was made from: the board is Hardware/TX_Board_Rev2/TX_Board_Rev2.kicad_pcb and its schematic Hardware/FiniteAntennaPatch/FiniteAntennaPatch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TX Board Rev2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask yilmaz-kaan before reusing the design.
