Questions
How big is the Bpsk modulator PCB?
It measures 66.5 × 42 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bpsk modulator use?
64 parts, built around the SYM-2500+, AD8055AN, AD9708AR and GALI-1. 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 Bpsk modulator KiCad files?
From the MTalon63/PCBs repository on GitHub, at the commit this page was made from: the board is bpsk-modulator/bpsk-modulator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bpsk modulator design in my own project?
Its repository states no licence, so its author keeps all rights: ask MTalon63 before reusing the design.
