Dspod u3c5: common questions

What microcontroller does the Dspod u3c5 use?

The Dspod u3c5 is built around the STM32U3C5RIT6, from the STM32 family.

How big is the Dspod u3c5 PCB?

The Dspod u3c5 measures 26.4 × 41.7 mm, has 4 copper layers and is 1.5313 mm thick.

How many components are on the Dspod u3c5?

49 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dspod u3c5 design files?

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

Can I use the Dspod u3c5 design in my own project?

Yes, under the terms of its MIT license, which emeb chose for the repository.

Can I test firmware for the Dspod u3c5 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.
