STM32 RF Demo: common questions
What microcontroller does the STM32 RF Demo use?
The STM32 RF Demo is built around the STM32WB55CEU6, from the STM32 family.
How big is the STM32 RF Demo PCB?
The STM32 RF Demo measures 58 × 31 mm, has 4 copper layers and is 1.62 mm thick.
How many components are on the STM32 RF Demo?
40 components, from 22 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 STM32 RF Demo design files?
From the Venky474/STM32_RF_Demo_PCB repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the STM32 RF Demo design in my own project?
Yes, under the terms of its MIT license, which Venky474 chose for the repository.
Can I test firmware for the STM32 RF Demo 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.
