TechnicalDocs openUC2-QBox: common questions
What microcontroller does the TechnicalDocs openUC2-QBox use?
The TechnicalDocs openUC2-QBox is built around the xiao_esp32s3, from the ESP32 family.
How big is the TechnicalDocs openUC2-QBox PCB?
The TechnicalDocs openUC2-QBox measures 106 × 46 mm, has 4 copper layers and is 1.6165 mm thick.
How many components are on the TechnicalDocs openUC2-QBox?
149 components, from 83 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 TechnicalDocs openUC2-QBox design files?
From the openUC2/TechnicalDocs-openUC2-QBox 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 TechnicalDocs openUC2-QBox design in my own project?
The repository has no license, so all rights stay with openUC2. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the TechnicalDocs openUC2-QBox 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.
