BmstuCtrlTree: common questions
What microcontroller does the BmstuCtrlTree use?
The BmstuCtrlTree is built around the STM32L476VC, from the STM32 family.
How big is the BmstuCtrlTree PCB?
The BmstuCtrlTree measures 71 × 40 mm, has 4 copper layers and is 1 mm thick.
How many components are on the BmstuCtrlTree?
146 components, from 35 distinct parts. The full bill of materials is listed on this page.
Where can I download the BmstuCtrlTree design files?
From the Kreyl/BmstuCtrlTree repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the BmstuCtrlTree design in my own project?
The repository has no license, so all rights stay with Kreyl. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the BmstuCtrlTree 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.
