Microscope camera: common questions

What microcontroller does the Microscope camera use?

The Microscope camera is built around the ComputeModule5-CM5, from the Raspberry Pi family.

How big is the Microscope camera PCB?

The Microscope camera measures 60 × 90 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Microscope camera?

43 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Microscope camera design files?

From the Morphdust/microscope_camera_pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Microscope camera design in my own project?

The repository has no license, so all rights stay with Morphdust. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Microscope camera 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.
