Voedings switcher: common questions
What microcontroller does the Voedings switcher use?
The Voedings switcher is built around the STM32L052K6Tx, from the STM32 family.
How many components are on the Voedings switcher?
19 components, from 16 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 Voedings switcher design files?
From the bendelathouwer/asset-tracker 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 Voedings switcher design in my own project?
The repository has no license, so all rights stay with bendelathouwer. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Voedings switcher 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.
