Steuerung: common questions
What microcontroller does the Steuerung use?
The Steuerung is built around the STM32WB5MMG, from the STM32 family.
How big is the Steuerung PCB?
The Steuerung measures 45 × 36.6 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the Steuerung?
45 components, from 30 distinct parts. The full bill of materials is listed on this page.
Where can I download the Steuerung design files?
From the Bergi84/GrowOMatic repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Steuerung design in my own project?
The repository has no license, so all rights stay with Bergi84. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Steuerung 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.
