DegraderDosimeter: common questions

What microcontroller does the DegraderDosimeter use?

The DegraderDosimeter is built around the STM32H723ZGTx, from the STM32 family.

How big is the DegraderDosimeter PCB?

The DegraderDosimeter has 4 copper layers and is 1.6 mm thick.

How many components are on the DegraderDosimeter?

197 components, from 52 distinct parts. The full bill of materials is listed on this page.

Where can I download the DegraderDosimeter design files?

From the ButiTando/23540850_TMahlati_2025_Skriptsie repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the DegraderDosimeter design in my own project?

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

Can I test firmware for the DegraderDosimeter 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.
