README.mdPD Trigger module on Hynetek HUSB238 chip
This is a rework of Hynetek HUSB238 evaluation board with minor changes. In general, i just added a fuse and reroute schematic for using available components from AliExpress.
The project is completed in Q4 2022.

Questions
How big is the PD trigger module PCB?
It measures 15.2 × 25.4 mm and has 2 copper layers, 0.8 mm thick.
What parts does the PD trigger module use?
33 parts, built around the AON7403. 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 PD trigger module KiCad files?
From the Freimor/HRDW-PDTrigger_HUSB238 repository on GitHub, at the commit this page was made from: the board is KiCad/PD_trigger_module.kicad_pcb and its schematic KiCad/PD_trigger_module-backups/PD_trigger_module-2022-09-27_124659/PD_trigger_module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PD trigger module 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).
