My next project is a BB-9. If anyone knows of it, I'm using the Joe Drive and 12v DC Planetary Motors with BTS7960 43A High Power Motor Driver H-Bridges. I'm using a 12V 20000mah battery for power.
If I power the EZ-b with 12v, can I run the power from the digital port straight to the H-bridge, or should I power it from the power source?
Thanks
If you are using a power base, there is a 20 amp fuse

If both motors pull more than 20 amp, you will end-up replacing the fuse.
There are other issues like wire gauges, you need to have proper wires to handle the motor amps.
My recommendation is to have separate circuits EZ-B and motor h-bridges.
you need to pickup the right wire gauge, and a fuse block something like this:

Ok thanks! I'll power them through a fuse panel.
Once I get it wired, I know I will have script questions.
Thanks, and i believe can be very relevant.
I missed that point, I wrongly assumed the VIN is connected to the Digital Ports Red Pin.
back to the lesson:

PCB:
EZB4:
one Schottky's diode (A7 T35) between the power in and the Vin. The 5 Amps must be diode max forward current.
Iotiny:
one Schottky's diode (A7 T63). I'm guessing ... the diode reference is different the limit must be different too.
Once again thanks for pointing out!
