XIAO Plus Base V1.0: common questions

What microcontroller does the XIAO Plus Base V1.0 use?

The XIAO Plus Base V1.0 is built around the XIAO-ESP32-S3-Plus-SMD, from the ESP32 family.

How big is the XIAO Plus Base V1.0 PCB?

The XIAO Plus Base V1.0 measures 42 × 35.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the XIAO Plus Base V1.0?

4 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the XIAO Plus Base V1.0 design files?

From the ppisljar/freeesp32_audioplayer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the XIAO Plus Base V1.0 design in my own project?

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

Can I test firmware for the XIAO Plus Base V1.0 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.
