Maslab: common questions

What microcontroller does the Maslab use?

The Maslab is built around the STM32F407VETX, from the STM32 family.

How big is the Maslab PCB?

The Maslab measures 99.1 × 99.1 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Maslab?

317 components, from 36 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 Maslab design files?

From the maslab-5/maslab 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 Maslab design in my own project?

The repository has no license, so all rights stay with maslab-5. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Maslab without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
