PS-HVCarrier: common questions
What microcontroller does the PS-HVCarrier use?
The PS-HVCarrier is built around the STM32L431CBTX, from the STM32 family.
How big is the PS-HVCarrier PCB?
The PS-HVCarrier measures 80.5 × 84.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PS-HVCarrier?
152 components, from 76 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 PS-HVCarrier design files?
From the lhr-solar/PS-HVCarrierPCB 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 PS-HVCarrier design in my own project?
The repository has no license, so all rights stay with lhr-solar. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PS-HVCarrier 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.
