Overview
Backplate is an open-source printed circuit board by hstarmans, from the hstarmans/firestarter repository on GitHub. It is a 2-layer board of 25.7 × 54.1 mm with 5 parts on 6 nets, routed with 14 tracks and 4 vias.
It belongs with the fPGA and programmable logic boards and the ESP32 and FPGA and CPLD boards of this library.
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 Backplate PCB?
It measures 25.7 × 54.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Backplate use?
5 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 Backplate KiCad files?
From the hstarmans/firestarter repository on GitHub, at the commit this page was made from: the board is lasermodule/backplate/backplate.kicad_pcb and its schematic base/camera.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Backplate design in my own project?
Its repository states no licence, so its author keeps all rights: ask hstarmans before reusing the design.
