Combined Fabrication: common questions
What microcontroller does the Combined Fabrication use?
The Combined Fabrication is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Combined Fabrication PCB?
The Combined Fabrication measures 92 × 82.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Combined Fabrication?
38 components, from 35 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 Combined Fabrication design files?
From the Cyberspecies/Synth-Head repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Combined Fabrication design in my own project?
The repository has no license, so all rights stay with Cyberspecies. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Combined Fabrication 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.
