README
lasermodule/laserdiode/README.mdLaser Diode Mount & Driver PCB
Carrier PCB for the laser diode module inside the scanhead housing. Provides pogo-pin connection to the back plate of the laserhead. Solder contacts provide opton to determine pin routing.
Key Details
- Function: Laser diode mounting and modulation interface
- Contacts: Spring-loaded pogo pin pads and direct solder pads for high-speed modulation driver connection
- Form Factor: Compact circular/rectangular footprint fitting diode heatsink assembly
Part of the Hexastorm (Firestarter) open-hardware laser direct imaging project.

Questions
How big is the Base PCB?
It measures 105.5 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Base use?
45 parts. 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 Base KiCad files?
From the hstarmans/firestarter repository on GitHub, at the commit this page was made from: the board is lasermodule/base/base.kicad_pcb and its schematic base/camera.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Base design in my own project?
Its repository states no licence, so its author keeps all rights: ask hstarmans before reusing the design.
