Strobe Light PCB

This repository contains the KiCad files for a high-power pulsed LED strobe board used for very short, very bright flashes during camera exposure.

Video script and notes:

  • strobe camera.md

Strobe KiCad Files

Main project folder:

  • KiCad/strobe-light/

Manufacturing outputs:

  • KiCad/strobe-light/manufacturing outputs/

Included fabrication files:

  • Gerbers (*-F_Cu.gbr, *-B_Cu.gbr, mask, paste, silkscreen, edge cuts)
  • Drill files (*-PTH.drl, *-NPTH.drl)
  • Job file (*.gbrjob)

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.
