VCU3.0: common questions

What microcontroller does the VCU3.0 use?

The VCU3.0 is built around the C2913204, from the ESP32 family.

How big is the VCU3.0 PCB?

The VCU3.0 measures 128.4 × 70.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the VCU3.0?

105 components, from 36 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 VCU3.0 design files?

From the milutintech/VCU 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 VCU3.0 design in my own project?

The repository has no license, so all rights stay with milutintech. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the VCU3.0 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
