PowerDistribution: common questions
What microcontroller does the PowerDistribution use?
The PowerDistribution is built around the STM32L431CBT6, from the STM32 family.
How big is the PowerDistribution PCB?
The PowerDistribution measures 90.2 × 96 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the PowerDistribution?
183 components, from 118 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 PowerDistribution design files?
From the UChicago-Space-Program/pulse-hardware 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 PowerDistribution design in my own project?
The repository has no license, so all rights stay with UChicago-Space-Program. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PowerDistribution 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.
