The KiCad project lives in the Benjamin-girard-1/magnetometer-node-old repository on GitHub; these links point at the commit this page was built from.

Untitled: common questions

What microcontroller does the Untitled use?

The Untitled is built around the ESP32-S3-DevKitC, from the ESP32 family.

How big is the Untitled PCB?

The Untitled measures 190 × 110 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Untitled?

269 components, from 69 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 Untitled design files?

From the Benjamin-girard-1/magnetometer-node-old 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 Untitled design in my own project?

The repository has no license, so all rights stay with Benjamin-girard-1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Untitled 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.
