Atx: common questions

What microcontroller does the Atx use?

The Atx is built around the STM32L151C8T6, from the STM32 family.

How big is the Atx PCB?

The Atx measures 170 × 170 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Atx?

53 components, from 22 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 Atx design files?

From the aep/pislice repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Atx design in my own project?

The repository has no license, so all rights stay with aep. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Atx 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.
