Eidon tracker: common questions

What microcontroller does the Eidon tracker use?

The Eidon tracker is built around the XIAO-ESP32-C6, from the ESP32 family.

How big is the Eidon tracker PCB?

The Eidon tracker measures 29.5 × 24.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Eidon tracker?

17 components, from 10 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 Eidon tracker design files?

From the Eidon-AI/eidon-tracker 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 Eidon tracker design in my own project?

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

Can I test firmware for the Eidon tracker 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.
