PercussiveInterface-3: common questions

What microcontroller does the PercussiveInterface-3 use?

The PercussiveInterface-3 is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the PercussiveInterface-3 PCB?

The PercussiveInterface-3 measures 460 × 97.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PercussiveInterface-3?

105 components, from 11 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 PercussiveInterface-3 design files?

From the lleck/PercussiveInterface-3 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 PercussiveInterface-3 design in my own project?

The repository has no license, so all rights stay with lleck. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PercussiveInterface-3 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.
