unfortunately the FPGA verilog source code isn't open source.. and I can't see any RF block diagram in the website

Some more questions because the website isn't clear:

- does the FPGA handle digital beamforming in the FPGA fabric? or it controls RF phase shifters for analog beamforming?

- will we have access to FPGA pin constraint file so we can write our own verilog

- can I get IQ samples from the antenna elements and run my own beamforming algorithm / calibration in a separate PC with possible GPU acceleration? or it will be bottlenecked by rpi5 gigabit ethernet?
