How to power stacked shields
I’d like to be running four NEMA-17s (ID 324) on two stacked Motor/Stepper/Servo shields (id: 1438). The question is how to power both shields.
Does the external 12v supplied to the first shield carry onto the second shield? Is it best to power them separately, that is independently of each other? Is it possible to power a third shield for 5v to drive Stepper Motor 32-Step (ID: 858)
Additionally, I’d like to stack a 16-Channel 12-bit PWM/Servo Shield - I2C interface
(ID: 1411) on top of the stepper shields. Should the servo shield be on its own power supply?

Re: How to power stacked shields
There is no pass-through for external power on the shields. You can share a supply if desired by daisy-chaining connections to the external power terminals between the shields. You can stack a servo shield on top of the motor shields. It can share power with one of the motor shields if the voltages are compatible.
One thing to be aware of when running several high-step-count motors: The maximum aggregate step-rate is limited by the speed of the i2c bus. There are instructions on how to increase this in the FAQ section of the guide.
