Hello All,
My first post on the Pololu forum will be a pretty simple one.
The website shows a PWM setup. The board shows what looks like 2 channels of control, with 2 PWM inputs and outputs. However, both channels are routed to a single motor. How do i interpret this?
Thank you for the help in advance.
Mark.
Hello.
Are you referring to our TB67H453FNG Single Brushed DC Motor Driver Carrier? If so, please note that it has a single motor channel as the name implies.
The motor output pins (OUT1 and OUT2) should connect to the two terminals of a brushed DC motor as shown in the minimal wiring diagrams.
There are two supported input modes. One accepts a digital signal for direction and a PWM signal for speed (i.e. sign-magnitude operation), and the other more advanced mode accepts two PWM signals, which allows you to achieve drive/coast or drive/brake operation. You can find more detailed information under the “Using the motor driver” heading of the product page linked above.
