HW designs

This is not an easy build and uses very small components.

I use a small oven which i bought from a local store, a microscope from ebay and solder paste from an online UK store. But if you are thinking of building this then i suspect that you already have the right tools.

The BOM file has all the part numbers listed either from RS Components or mouser (the 2 component suppliers i use), You do not have to buy from there but adding the part numbers to the RS website search will bring up the item page which has all the info. The components can be bought from where ever you like.

QUarkNano 9250: common questions

What microcontroller does the QUarkNano 9250 use?

The QUarkNano 9250 is built around the STM32F405RGT6, from the STM32 family.

How big is the QUarkNano 9250 PCB?

The QUarkNano 9250 measures 21.5 × 30 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the QUarkNano 9250?

60 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the QUarkNano 9250 design files?

From the ukmook/qUark repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the QUarkNano 9250 design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which ukmook chose for the repository.

Can I test firmware for the QUarkNano 9250 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.
