BmstuCtrl: common questions

What microcontroller does the BmstuCtrl use?

The BmstuCtrl is built around the STM32L151CXTX, from the STM32 family.

How big is the BmstuCtrl PCB?

The BmstuCtrl measures 70 × 52 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BmstuCtrl?

82 components, from 34 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 BmstuCtrl design files?

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

Can I use the BmstuCtrl 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 BmstuCtrl 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.
