Laser nephelometer: common questions

What microcontroller does the Laser nephelometer use?

The Laser nephelometer is built around the RP2354B, from the Raspberry Pi family.

How big is the Laser nephelometer PCB?

The Laser nephelometer measures 56.6 × 57.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Laser nephelometer?

103 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the Laser nephelometer design files?

From the sai-ydev/laser_nephelometer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Laser nephelometer design in my own project?

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

Can I test firmware for the Laser nephelometer without the hardware?

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