Qnot1: common questions
What microcontroller does the Qnot1 use?
The Qnot1 is built around the STM32F405RGTx, from the STM32 family.
How big is the Qnot1 PCB?
The Qnot1 measures 34 × 34 mm, has 8 copper layers and is 1.6 mm thick.
How many components are on the Qnot1?
211 components, from 65 distinct parts. The full bill of materials is listed on this page.
Where can I download the Qnot1 design files?
From the SushEdge/Qnot1 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Qnot1 design in my own project?
The repository has no license, so all rights stay with SushEdge. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Qnot1 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
