SMDU: common questions

What microcontroller does the SMDU use?

The SMDU is built around the STM32F303K8TX, from the STM32 family.

How big is the SMDU PCB?

The SMDU measures 77.6 × 30.1 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the SMDU?

81 components, from 34 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 SMDU design files?

From the sabanekko3/sMDU_PCB 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 SMDU design in my own project?

The repository has no license, so all rights stay with sabanekko3. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SMDU 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.
