UpLink was a 491-gram high altitude balloon payload with a custom 3D printed enclosure, a LoRa image downlink, and two independent trackers. It reached the stratosphere, sent back hundreds of pictures, and we never recovered it.

Questions
How big is the UpLink PCB?
It measures 30 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UpLink use?
37 parts, built around the SAM-M10Q-00B, MCP3204-CI/P and CSS-1210TB. 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 UpLink KiCad files?
From the radeeyate/UpLink repository on GitHub, at the commit this page was made from: the board is hardware/UpLink.kicad_pcb and its schematic hardware/UpLink.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UpLink design in my own project?
Its repository states no licence, so its author keeps all rights: ask radeeyate before reusing the design.
