PUEiE: common questions

What microcontroller does the PUEiE use?

The PUEiE is built around the STM32WLE5C8Ux, from the STM32 family.

How big is the PUEiE PCB?

The PUEiE measures 48.3 × 31.6 mm, has 2 copper layers and is 1.59 mm thick.

How many components are on the PUEiE?

56 components, from 38 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 PUEiE design files?

From the Michal-Md/PUEiE 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 PUEiE design in my own project?

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

Can I test firmware for the PUEiE 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.
