Universal motor driver need input

Hello. I have the new Universal motor driver 64010 Rev B. I have looked over the UniversalMotorDriver P2 add on guide-V.1.1. I am trying to get it running. I have used the HB-25 motor control and I love it. But as soon as I find something I like it is no longer available. I wright simple code for the HB-25 and it works like fantastic. Is the Universal motor driver 64010 Rev B anything like the HB-25???? Where do I input the PWM to what pin??? There are 15 input pins with no pins. Could someone take me by the hand and show me where the pins are to input the PWM (plus with modulation). I have already found the ground pin. Can I use the same code that I use to run the HB-25 on the Propeller 1 (one)?? Is there a demonstration video some where out there??? Or some other paper work that I do not know about?? Thank you very much for any help in this matter. 18nov2025(tue)

Have you seen the product page?

This unit is nothing like the HB-25. It can drive BLDC type motors as well as standard motors.
I assume you have the original Motor Mount and Wheel Kit.
Someone should have built code to run those motors.

Hello and thank you for your input. Mr. Rayman I have the documentation that you listed and I have been trying to make heads and tales of it but the going is slow. Mr. iseries your input tells me that I must try a different direction. It took me 3 months to get the HB-25 going and this may take longer. I thank both of you for your time. 20nov 2025(thur)
Hello . Still need input for the Universal motor driver. The blue print with the pin output it is not a mach for what is on the circuit board. The blue print for the connections do not show the pin out for the integrated circuit. What pin do I hook up the pulse with modulation input to is it pin 1 through 15??? I am trying to down load a pitcher but no can find the paper clip for attachments
I tried to drag and drop a pitcher and all this stuff came up?

Perhaps Parallax might want to put together a tutorial, how to connect a pair of brushed motors to P2 via this board?
Maybe you already have, but in case you haven't... Have you reviewed the driver repo for the driver that Chip and I put together for the board?
See BLDC Motor Driver repository
Stephen, have you had a look at the hb-25 driver, that he wants to replace. It is for brushed motors!!!

Have you seen this example with DC motors: https://www.parallax.com/arlo-conversion-to-p2-with-the-universal-motor-controller/
Although it uses Arlo motors, they are simple DC motors, and the wiring and code example could provide the clues you are searching for ?
You might ignore the encoder wiring- those are not needed to drive motors.
Having a quick look, the demo as shown wires the two DC motors so they use all four motor channels. That allows the motors to be controlled forwards or backwards.
If you only needed a single rotation direction, and if you wanted to connect up to four DC motors, then could could wire your motor +ve cables all direct to your battery, and connect the motor -ve/GND cables to each of the Universal Motor Driver channels (U,V,W,X). Thus you'd set the motor output low to turn the motor on, and high to stop the motor. (By "set the motor output low", I mean, enable the corresponding PWM signal; ie. PWM_UL to set the U output low (the code example in the above linked demo has the detail on this).
Well, you are right, I had not understood the difference...
