Is there a wifi module out there that can be soldered onto the Rhino?
Rhino only takes the WIZ811 module for wired ethernet. I’ve never seen a wireless module that’s even remotely capable of drop-in replacement (but admittedly never deliberately searched for one either). Bigger issue is that you’ll have to have it cope with the entire IP stack because the USBizi doesn’t implement the stack; that might be hard to find!
You can use the wifi bridge we offer
