Capacitance: common questions

What microcontroller does the Capacitance use?

The Capacitance is built around the STM32U545RETxQ, from the STM32 family.

How big is the Capacitance PCB?

The Capacitance measures 58.8 × 58.8 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Capacitance?

69 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Capacitance design files?

From the ihsan92UM/Project-work repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Capacitance design in my own project?

The repository has no license, so all rights stay with ihsan92UM. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Capacitance 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.
