Casing of HolyBro F9P Rover Lite GPS Modules

Good day everyone,

Is the casing of HolyBro H-RTK F9P Rover lite (SKU12017) & H-RTK F9P Rover lite 2nd GPS (SKU12025) weatherproof/waterproof/water resistant?

I’m not able to find any concrete info on it. Any help/ experience sharing will be appreciated.

Thanks!
