VCU CM5: common questions
What microcontroller does the VCU CM5 use?
The VCU CM5 is built around the STM32F103CBT6, from the STM32 family.
How big is the VCU CM5 PCB?
The VCU CM5 measures 100 × 90 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the VCU CM5?
418 components, from 116 distinct parts. The full bill of materials is listed on this page.
Where can I download the VCU CM5 design files?
From the NTURacingTeam/nturt_kicad_EP7 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the VCU CM5 design in my own project?
The repository has no license, so all rights stay with NTURacingTeam. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the VCU CM5 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.
