Dome Controller: common questions
What microcontroller does the Dome Controller use?
The Dome Controller is built around the ESP32-WROOM-32D-N16, from the ESP32 family.
How big is the Dome Controller PCB?
The Dome Controller measures 136.5 × 70 mm, has 4 copper layers and is 4.69 mm thick.
How many components are on the Dome Controller?
33 components, from 28 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 Dome Controller design files?
From the greghulette/KiCad-Files-Public 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 Dome Controller design in my own project?
The repository has no license, so all rights stay with greghulette. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Dome Controller 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.
