Hvsd-3ch: common questions
What microcontroller does the Hvsd-3ch use?
The Hvsd-3ch is built around the STM32G473QET6, from the STM32 family.
How big is the Hvsd-3ch PCB?
The Hvsd-3ch measures 109 × 231.4 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Hvsd-3ch?
457 components, from 57 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 Hvsd-3ch design files?
From the ExcessiveOverkill/hvsd-3ch 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 Hvsd-3ch design in my own project?
The repository has no license, so all rights stay with ExcessiveOverkill. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Hvsd-3ch 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.
