Hi  
I own a pidog. I’d like to add a couple more 5v sensors, but I’m not sure, after supplying the servos, how much additional current I can draw from the remaining 5v servo supplies on the hat. Can anyone please advise?

There is barely any extra power left. The robotic dog struggles to stand up when performing small extreme movements, so there is hardly any additional current available to drive other components. Therefore, we do not recommend adding more sensors.

If you do want to add something, small sensors should be fine.

Thank you, I’ll not add anything more.
