Pi4 direct connect to Einsy Undervolt?

I followed the diagrams and connected the Pi4 to the Einsy and now I get undervolt warnings and throttled warnings. do I need a separate power supply for the pi4? should I power it via the USB-C and disconnect the 5v in from the Einsy? add a capacitor?

Thoughts?

The Pi4 draws a hell of a lot more power than I'd want to suck off the Einsy. Definitely use a separate power supply.

Separate USB-C power supply for the Pi immediately. Remove the +5V power connection between the pi and the Einsy, and leave the ground connection if you want to use GPIO TX/RX ......or remove it all and plug in the USB cable.
