Help with PiDog and Raspberry Pi5

[TheRealMikeWayne]

If anyone would help Thank you in advance; Im not the most experienced. I Love this PiDog kit and want to learn more. Im using a Pi5 (Sunfounder doesn’t list it as compatible. Im under the impression newer Pi’s are compatible with older kits?) I have almost all examples working, even the phone app, but when it got to move more than one servo at a time the Pi turns off. I have disabled the usb current in the menu as well as: sudo raspi-config. I guess I’m go to order a Pi 4 to see if this is the issue.

The problem with the pi 5 is its energy consumption, when you turn on the pidog and put it to work you can notice that when you get up the raspberry turns off, because the robot hat is not capable of supplying the necessary energy for the pi 5, I had the Same problem and I had to solve it by buying a Pi 4, but even if you buy the Pi 4 you will quickly notice that you can't do much with the servos since they are of poor quality and do not support the weight of the Pidog well.

Two things I figured out about this:

1. Yes the Pi5 draws too much power, but (in theory, I haven't done it myself) you could disable the 5v HAT Pins and power the Pi5 independently, then it's power draw won't affect the robot parts. This will give the servos more power and also protect the Pi from brown outs caused by server.

2. You can add capacitors to your 5v rail on the robot hat to buffer the power spikes caused by multiple servos firing at once. 2 3300uf 10V Capacitors wired into 5v and gnd servo rails fixed my pidog and now it doesn't shut down.

It all seemed to be working for me until I tried some more advanced scripts and then I see the brown outs. How should i go about adding the capacitor? it seems the servos take up all the rails. I suppose I could unplug something non-critical like the tail
