Questions
How big is the Combo laser driver PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Combo laser driver use?
169 parts, built around the RP2040, LM2576S-ADJ, LM324 and W25Q128JVSIQ. 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 Combo laser driver KiCad files?
From the adeboni/laser-projector repository on GitHub, at the commit this page was made from: the board is 2024/hardware/combo_laser_driver/combo_laser_driver.kicad_pcb and its schematic 2023/hardware/15v_power/15v_power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Combo laser driver design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
