BlueBuzzah-Hardware: common questions

What microcontroller does the BlueBuzzah-Hardware use?

The BlueBuzzah-Hardware is built around the XIAO-ESP32-S3-SMD, from the ESP32 family.

How big is the BlueBuzzah-Hardware PCB?

The BlueBuzzah-Hardware measures 42 × 42 mm, has 2 copper layers and is 1.6062 mm thick.

How many components are on the BlueBuzzah-Hardware?

59 components, from 13 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 BlueBuzzah-Hardware design files?

From the BlueBuzzah/BlueBuzzah-Hardware 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 BlueBuzzah-Hardware design in my own project?

Yes, under the terms of its MIT license, which BlueBuzzah chose for the repository.

Can I test firmware for the BlueBuzzah-Hardware 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.
