XIAO-ESP32-S3-MES: common questions
What microcontroller does the XIAO-ESP32-S3-MES use?
The XIAO-ESP32-S3-MES is built around the XIAO-ESP32-S3-SMD, from the ESP32 family.
How big is the XIAO-ESP32-S3-MES PCB?
The XIAO-ESP32-S3-MES measures 39 × 43 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the XIAO-ESP32-S3-MES?
12 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 XIAO-ESP32-S3-MES design files?
From the RRST-NHK-Project/kicad-ws 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 XIAO-ESP32-S3-MES design in my own project?
The repository has no license, so all rights stay with RRST-NHK-Project. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the XIAO-ESP32-S3-MES 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.
