Notes:
- For PCB ordering, use the files in
KiCad/strobe-light/manufacturing outputs/. - Check BOM entries for specific manufacturer part numbers of certain components.
Strobe Use
- Powered by a 24vdc supply, I used a 6A adapter, but 1A should work fine (untested).
- If using long strobe durations or high pulse frequencies, beware of thermals. In my testing I did not exceed 250us @ 40hz.
- Trigger input signal is a 5v differential pair, any RS485 or RS422 transmitter should work.
- The EFUSE limits inrush to avoid tripping overcurrent protection on small power adapters. Ready when status LED is OFF.
- EFUSE will also trip if you attempt to run the LEDs continuously.
Camera Controller Status
The camera controller board in KiCad/camera-controller/ is included for reference, but it currently needs fixes before it should be considered production-ready.
Safety
Don't stare at the light.

Questions
How big is the Strobe light.kicad pro PCB?
It measures 93.4 × 70.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Strobe light.kicad pro use?
90 parts, built around the THVD1420D and L7805. 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 Strobe light.kicad pro KiCad files?
From the ExcessiveOverkill/strobe-camera repository on GitHub, at the commit this page was made from: the board is KiCad/strobe-light/strobe-light.kicad_pro/strobe-light.kicad_pro.kicad_pcb and its schematic KiCad/camera-controller/camera-controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Strobe light.kicad pro design in my own project?
Its repository states no licence, so its author keeps all rights: ask ExcessiveOverkill before reusing the design.
