DangerDoughnut: common questions
What microcontroller does the DangerDoughnut use?
The DangerDoughnut is built around the ESP32-S3, from the ESP32 family.
How big is the DangerDoughnut PCB?
The DangerDoughnut measures 50 × 37 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the DangerDoughnut?
152 components, from 84 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 DangerDoughnut design files?
From the gavin4d/dangerDoughnut 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 DangerDoughnut design in my own project?
The repository has no license, so all rights stay with gavin4d. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the DangerDoughnut 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.
