Questions
How big is the Jammer Front End PCB?
It measures 85.6 × 54 mm and has 4 copper layers, 1.5 mm thick.
What parts does the Jammer Front End use?
116 parts, built around the LT8336EV#PBF, ADP7156ACPZ-2.5-R7, ADP7156ACPZ-3.3-R7 and ADP7183ACPZN2.5-R7. 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 Jammer Front End KiCad files?
From the adrianiaz/Jammer_Front_End repository on GitHub, at the commit this page was made from: the board is KiCad_files/Jammer_Front_End.kicad_pcb and its schematic KiCad_files/ADMV8818.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Jammer Front End design in my own project?
Its repository states no licence, so its author keeps all rights: ask adrianiaz before reusing the design.
