Power systems: common questions
What microcontroller does the Power systems use?
The Power systems is built around the LM5050MK-1/NOPB, from the NXP family.
How big is the Power systems PCB?
The Power systems measures 65.5 × 93 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Power systems?
50 components, from 30 distinct parts. The full bill of materials is listed on this page.
Where can I download the Power systems design files?
From the Purdue-Space-Program/PSPL_R4_Avionics_Hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Power systems design in my own project?
The repository has no license, so all rights stay with Purdue-Space-Program. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Power systems without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
