Questions
How big is the BackPanel PCB?
It measures 112 × 125.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BackPanel use?
51 parts, built around the R-78B3.3-2.0. 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 BackPanel KiCad files?
From the w4kpm/TrackerReplacement repository on GitHub, at the commit this page was made from: the board is KiCad/TrackerBackPanel/BackPanel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BackPanel design in my own project?
Its repository states no licence, so its author keeps all rights: ask w4kpm before reusing the design.
