Hi Jan,

Ok, no worries. Thanks you for the help. All sorted by reinstalling the 32-bit version.

Cheers

Mike

Hi Mike,
sorry for the late reply. To be honest, I haven't tried Monarco HAT with PoE HAT. However, by specification, HAT devices are not generally stackable. Monarco HAT should be powered by 10-30 VDC. PoE HAT supplies only 5 VDC. So I don't think it will work.
Cheers,
Jan
