VCU: common questions

What microcontroller does the VCU use?

The VCU is built around the ESP32-WROOM-32U, from the ESP32 family.

How big is the VCU PCB?

The VCU measures 60.5 × 100.5 mm, has 4 copper layers and is 1.1842 mm thick.

How many components are on the VCU?

160 components, from 67 distinct parts. The full bill of materials is listed on this page.

Where can I download the VCU design files?

From the matatma23-gento/embedded-portfolio 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 design in my own project?

The repository has no license, so all rights stay with matatma23-gento. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the VCU 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.
