Batch (4 Layer SMT): common questions
What microcontroller does the Batch (4 Layer SMT) use?
The Batch (4 Layer SMT) is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Batch (4 Layer SMT) PCB?
The Batch (4 Layer SMT) measures 100 × 100 mm, has 4 copper layers and is 0.8192 mm thick.
How many components are on the Batch (4 Layer SMT)?
68 components, from 52 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 Batch (4 Layer SMT) 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 Batch (4 Layer SMT) 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 Batch (4 Layer SMT) 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.
