STM32WB5MMGH6TR and STM32WL5MOC on the same board

matteverze · ‎2025-07-31

Hi,

I want to integrate on the same PCB both a STM32WB5MMGH6TR and a STM32WL5MOC. Are there any issue in terms of RF interference? Are there any shielding recommendations to avoid problems while both modules are transmitting?

Thanks

Matteo

Most (all?) of the issues would be generic to co-locating any sub-GHz radio with any 2.4GHz radio - not specific to STM32.

So have you tried a general internet search on that?

eg, look at Amazon Sidewalk ...

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
