V1 XIAO MAINBOARD: common questions
What microcontroller does the V1 XIAO MAINBOARD use?
The V1 XIAO MAINBOARD is built around the Module_XIAO-ESP32S3, from the ESP32 family.
How big is the V1 XIAO MAINBOARD PCB?
The V1 XIAO MAINBOARD measures 91.3 × 59 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the V1 XIAO MAINBOARD?
14 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the V1 XIAO MAINBOARD design files?
From the NB6RULES/Nadec-Biju-Fabacademy-Files repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the V1 XIAO MAINBOARD design in my own project?
The repository has no license, so all rights stay with NB6RULES. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the V1 XIAO MAINBOARD 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.
