I have a Sabortooth 2x5 for a Johnny 5 robot kit. I’m feeding it an analog signal for its inputs.
and the motors are not driving.
I’ve verified 0-5 volts on the S0 and S1 inputs. At power up I see a pwm signal (12 volts) on the motor for ~2 seconds, then it goes away.
Then settles down to 5 volts.
The blue LED is on, Red is off.
The board was shipped with 3 pwm connectors instead of terminal block as shown in the diagram.
I removed them and soldered my signal directly to S0 & S1 inputs, and ground.
Thanks for any help
