Compatibility of X-NUCLEO-IKS4A1 with X-NUCLEO-WB05KN1 or other BLE Expansion Options?

[Duc]

Hello STM Community,

I currently have a NUCLEO-U575ZI-Q board and the X-NUCLEO-IKS4A1 motion MEMS and environmental sensor expansion board. I’m looking to add BLE functionality and was considering the X-NUCLEO-WB05KN1.

Before proceeding, I’d like to ask:

1. Are the X-NUCLEO-IKS4A1 and X-NUCLEO-WB05KN1 compatible when stacked together on the NUCLEO-U575ZI-Q?

2. If not, is there an alternative BLE expansion board that is known to work well with the IKS4A1 on this Nucleo board?

3. Alternatively, is there an expansion or adapter board that allows both shields to be connected without pin conflicts?

Any guidance or shared experience would be greatly appreciated!

Thanks in advance.

Look at the User Manuals and/or Schematics for the two boards - they will tell you what pins they use and, thus, if there are any conflicts.

• User Manuals can be found on the 'Documentation' tab of the board's Product Page;
  eg, https://www.st.com/en/evaluation-tools/x-nucleo-iks4a1.html#documentation
• Schematics will be on the 'CAD Resources' tab;
