The KiCad project lives in the icl-rocketry/VLAD-CanSat repository on GitHub; these links point at the commit this page was built from.

VLAD-CanSat: common questions

What microcontroller does the VLAD-CanSat use?

The VLAD-CanSat is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the VLAD-CanSat PCB?

The VLAD-CanSat measures 90 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the VLAD-CanSat?

84 components, from 45 distinct parts. The full bill of materials is listed on this page.

Where can I download the VLAD-CanSat design files?

From the icl-rocketry/VLAD-CanSat repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the VLAD-CanSat design in my own project?

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

Can I test firmware for the VLAD-CanSat 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.
