Kronos-Hardware: common questions
What microcontroller does the Kronos-Hardware use?
The Kronos-Hardware is built around the ESP32-S3-MINI-1, from the ESP32 family.
How big is the Kronos-Hardware PCB?
The Kronos-Hardware measures 65.6 × 91.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Kronos-Hardware?
144 components, from 21 distinct parts. The full bill of materials is listed on this page.
Where can I download the Kronos-Hardware design files?
From the AddeyX/Kronos-Hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Kronos-Hardware design in my own project?
The repository has no license, so all rights stay with AddeyX. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Kronos-Hardware 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.
