Jazz: common questions

What microcontroller does the Jazz use?

The Jazz is built around the XIAO-ESP32-S3-DIP, from the ESP32 family.

How big is the Jazz PCB?

The Jazz measures 38.5 × 30.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Jazz?

20 components, from 17 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 Jazz design files?

From the devisunofficial/Jazz 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 Jazz design in my own project?

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

Can I test firmware for the Jazz 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.
