With the recent focus of attention towards remote work and mobile computing, the possibility of taking a powerful workstation wherever needed is enticing. However, even emerging laptops today struggle to compete with desktops in terms of cost, maintenance, and future upgrades. The price point of a powerful laptop is considerably higher compared to an equally powerful desktop computer, and most laptops are manufactured in a way that makes upgrading parts of the machine difficult or impossible, forcing a complete purchase in the…

Thesis: common questions

What microcontroller does the Thesis use?

The Thesis is built around the ComputeModule4-CM4, from the Raspberry Pi family.

How big is the Thesis PCB?

The Thesis measures 158.3 × 110 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Thesis?

78 components, from 44 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 Thesis design files?

From the Dylancyclone/thesis 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 Thesis design in my own project?

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

Can I test firmware for the Thesis 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.
