Trotten: common questions
What microcontroller does the Trotten use?
The Trotten is built around the ADAFRUIT-ESP32-S3, from the ESP32 family.
How big is the Trotten PCB?
The Trotten measures 75.8 × 60.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Trotten?
20 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the Trotten design files?
From the Oberson-Antoine/Trotten-Electric-Table repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Trotten design in my own project?
The repository has no license, so all rights stay with Oberson-Antoine. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Trotten 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.
