Hey all, have a mobility scooter bought from the restore for 50 bucks. It had one bad battery which I replaced but still no go. I can jump 24v to the motor and it works.
Have checked the safety and brake circuits-ok. I think it’s the little controller board. The board is about 300 dollars and I’m looking at a better option.
I would like to use:
I’d use the existing wig wag direction control with the 5v output, to control the direction. It has a 5v pot on the wig wag. There’s also a speed control pot wired in series with the wiper on the direction pot.
Issues I could see are the neutral needs to be 2.5v, so does this unit I linked have any sort of dead band or is it just 2.5v exactly?
Also, I know I’ll need to have a brake switch etc.
I’d prefer to use an aio controller like this that I don’t need to program if possible.
I also like the idea of this motor controller as I could in the future use higher voltage if we need to supe this little scooter up
The first thing you should take into account is if the current rating is enough for your scooter. If you are unsure these guides should help you out:
Also, the motor driver you linked only works for one motor, if you’d like to control two motors independently you’ll need a driver with more channels. And if you are using the same channel for more than one motor you’ll also need to take that into account for the current rating.

The documentation doesn’t mention any sort of dead band.
Locked Anti-Phase – Motor stops when the input signal is 2.5V. Motor moves in one direction when the input is < 2.5V and in another direction when the input is > 2.5V
But if you’d like you can contact the manufacturer and ask directly:
