[PSUBS-MAILIST] speed controller

Wed Nov 2 11:33:17 EDT 2016

I've built a couple of robots using speed controllers from these guys
https://www.dimensionengineering.com/products/sabertooth2x60

Very good stuff, very robust with over-current, thermal, and short circuit
protection. The one I linked to is there top of the line, twin channel
speed controller. It will supply 2 DC motors up to 60A EACH. They also have
lower current rated ones. They come with all of the bells and whistles. You
can do linear or exponential control through 2 channels of mixed or unmixed
RC or 2 channels of analog 0-5 input.

I've used these controllers extensively for a while now. They are really
neat. The big issue is that it doesn't do 36V systems. Which leaves quite a
few psubbers standing out in the rain,
