There is a littel production error. The GND Connection of the D1, U1 and L1 aren't done correctly. So to make the step-down converter work, simply solder a GND bridge on top of the pins of the step-down converter, like seen on the Picture.
This is the imporved Raspberry Pi HAT based on my other product: HAT rev1.0
This stepper driver HAT has an additional step-down converter on it. so it's possible to run the driver at a higher voltage and get the benefit to simultaneously power the Raspberry Pi at 5VDC. No additional 5V power supply necessarily.
I made it for my own project. a simple vending machine, which is driven by a NEMA17 stepper motor. I built it based on my first version of the PCB, which had no step-down converter. The Main reason i made a second version was so i could power the Raspberry Pi and the stepper driver/motor with a single power supply.
It's a two in one stepper driver HAT and step-down converter. Simply power motor and driver at a higher voltage, like 24VDC and let the onboard step-down converter supply the 5VDC for the Raspberry Pi
Raspberry Pi and stepper driver module are not included.
