Echo Show 5 - 3rd gen serial data

I recently received a new Echo show 5 that kept rebooting during setup. The screen would not respond to touch after choosing the wifi network.

After searching to see if others had issues, found a post here about jailbreaking the device.

I’m not interested in using the device for anything else but thought about what those 9 pads were used for.

I started sampling all pads on the main PCB and found two pads that have what appears to be serial TX.

Decoding doesn’t produce much.

I’ll solder probes directly to the pads next & try other protocols.
