Overview
Camera controller is an open-source printed circuit board by ExcessiveOverkill, from the ExcessiveOverkill/strobe-camera repository on GitHub. It is a 2-layer board of 82 × 35 mm with 28 parts on 42 nets, routed with 136 tracks and 79 vias.
It is built around the THVD1420D and D1213A-04S-7-ES. Its parts include 8 resistors, 5 diodes, 5 connectors, 2 ICs and 2 switches. It belongs with the AVR (ATmega, ATtiny) boards of this library.

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.

Questions
How big is the Camera controller PCB?
It measures 82 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Camera controller use?
28 parts, built around the THVD1420D and D1213A-04S-7-ES. 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 Camera controller KiCad files?
From the ExcessiveOverkill/strobe-camera repository on GitHub, at the commit this page was made from: the board is KiCad/camera-controller/camera-controller.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 Camera controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask ExcessiveOverkill before reusing the design.
