SpeakerSystem: common questions

What microcontroller does the SpeakerSystem use?

The SpeakerSystem is built around the ESP32-DevKitC, from the ESP32 family.

How big is the SpeakerSystem PCB?

The SpeakerSystem measures 100 × 76 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SpeakerSystem?

44 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the SpeakerSystem design files?

From the Chill-Sam/SpeakerSystem repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SpeakerSystem design in my own project?

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

Can I test firmware for the SpeakerSystem 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.
