Organization
There is a folder for each subsystem. Within each subsystem folder are hardware and firmware folders. Put hardware related files into the hardware folder, firmware in the firmware folder. Other folders can be added as needed: for example a media folder is handy for storing pictures related to a project which can be used in documentation.
Conventions
Partly for consistency, partly for functionality; please follow the following conventions:
- Try to keep folder names to single words and all lowercase
- Use underscores to separate words in names (e.g.
board_rev1). DO NOT USE SPACES! ESPECIALLY FOR FOLDERS CONTAINING CODE! Spaces in file paths may cause issues in compilers and such so best to avoid them entirely.

Questions
How big is the Downlink board PCB?
It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Downlink board use?
56 parts, built around the NRF24L01 and TPS563208DDCR-MS. 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 Downlink board KiCad files?
From the hpvdt/typhoon_electronics repository on GitHub, at the commit this page was made from: the board is telemetry/hardware/downlink_board_version2/downlink_board.kicad_pcb and its schematic environmentals/hardware/env_sens_Kicad/env_sens.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Downlink board design in my own project?
Its repository states no licence, so its author keeps all rights: ask hpvdt before reusing the design.
