CDM 324 radar module with RPI zero issue

Hello,

I connected a CDM324 module on a pi zero. I use the power supply from the RPI zero to power the CDM324 module.

In that configuration, the module doesn’t work correctly: it sees movements which don’t exist…
When I shutdown the module, the problem disapear…

Does somebody use this module with a PI, even this issue?

Thank you in advance,
Arnaud
