STM32WB-DEV-BOARD: common questions
What microcontroller does the STM32WB-DEV-BOARD use?
The STM32WB-DEV-BOARD is built around the STM32WB55CEU6, from the STM32 family.
How big is the STM32WB-DEV-BOARD?
The STM32WB-DEV-BOARD measures 30.2 × 50 mm, has 4 copper layers and is 1.48 mm thick.
How many components are on the STM32WB-DEV-BOARD?
48 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the STM32WB-DEV-BOARD design files?
From the MohamedSharfi/STM32WB-DEV-BOARD repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the STM32WB-DEV-BOARD design in my own project?
The repository has no license, so all rights stay with MohamedSharfi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the STM32WB-DEV-BOARD 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.
