Pewpew laserboard: common questions

What microcontroller does the Pewpew laserboard use?

The Pewpew laserboard is built around the TEENSY41, from the NXP family.

How big is the Pewpew laserboard PCB?

The Pewpew laserboard measures 80 × 95 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pewpew laserboard?

119 components, from 34 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 Pewpew laserboard design files?

From the matthewSorensen/pewpew-laserboard 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 Pewpew laserboard design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which matthewSorensen chose for the repository.

Can I test firmware for the Pewpew laserboard 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.
