QC Hack wPins: common questions
What microcontroller does the QC Hack wPins use?
The QC Hack wPins is built around the ATTINY412-SS, from the AVR/Arduino family.
How big is the QC Hack wPins PCB?
The QC Hack wPins measures 26.1 × 31.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the QC Hack wPins?
15 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 QC Hack wPins design files?
From the Fab-Lab-Island/fli-bootcamp-2025 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 QC Hack wPins design in my own project?
The repository has no license, so all rights stay with Fab-Lab-Island. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the QC Hack wPins without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
