Combo laser driver: common questions

What microcontroller does the Combo laser driver use?

The Combo laser driver is built around the AMS1117-3.3, from the RP2040/RP2350 family.

How big is the Combo laser driver PCB?

The Combo laser driver measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Combo laser driver?

165 components, from 60 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Combo laser driver design files?

From the adeboni/laser-projector repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Combo laser driver design in my own project?

Yes, under the terms of its GPL-3.0 license, which adeboni chose for the repository.

Can I test firmware for the Combo laser driver without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
