AlphaMod32: common questions

What microcontroller does the AlphaMod32 use?

The AlphaMod32 is built around the STM32F072C8Tx, from the STM32 family.

How big is the AlphaMod32 PCB?

The AlphaMod32 measures 214.3 × 77.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AlphaMod32?

79 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the AlphaMod32 design files?

From the marksard/alphamod32 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the AlphaMod32 design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which marksard chose for the repository.

Can I test firmware for the AlphaMod32 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.
