4x laser controller: common questions

What microcontroller does the 4x laser controller use?

The 4x laser controller is built around the Teensy4.1, from the NXP family.

How big is the 4x laser controller PCB?

The 4x laser controller measures 70.8 × 100 mm, has 4 copper layers and is 1.69 mm thick.

How many components are on the 4x laser controller?

138 components, from 29 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 4x laser controller 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 4x laser controller 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 4x laser controller without the hardware?

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