Questions
How big is the HoG Telemetry PCB?
It measures 33.6 × 65.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HoG Telemetry use?
99 parts, built around the PE4259-63, SX1262IMLTRT and AMS1117-3.3. 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 HoG Telemetry KiCad files?
From the GoTouchGra55/HoG repository on GitHub, at the commit this page was made from: the board is Kicad/Telemetry/HoG_Telemetry.kicad_pcb and its schematic Kicad/FC/HoG.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HoG Telemetry design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
