Bluephil STM32WB555: common questions

What microcontroller does the Bluephil STM32WB555 use?

The Bluephil STM32WB555 is built around the STM32WB55CEU6, from the STM32 family.

How big is the Bluephil STM32WB555 PCB?

The Bluephil STM32WB555 measures 44.3 × 24.1 mm, has 4 copper layers and is 1.58 mm thick.

How many components are on the Bluephil STM32WB555?

40 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bluephil STM32WB555 design files?

From the Chockalingam-M/PCB-Designing repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Bluephil STM32WB555 design in my own project?

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

Can I test firmware for the Bluephil STM32WB555 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.
