Hi Colombo,

Digital isolators should be good here. Check this part out: www.ti.com/.../ISO7221C

Hi Sal ,

please I do not think it could work , on USB you need to handle bidirectionallity and this is not capable .

coudl you check ?

thank you

The part is very much bi-directional Carlo!

Hi Gautam
my concern on bidirectional is if the ISO is handling all timing , idle tec totally transparent to the mcu .
thank you
