These
Or for more suppliers, try This Search
Has anyone tried these? I can't quite figure out why they need to use so many ICs, so they won't be the ultimate in small size or weight - but they are cheap, they even give boards from standard servos a run for their money in terms of cost.
There seem to be versions available with or without braking, but as a build/order option rather than a user selection.
I can't figure out what the attached switch might be for...

Brushed motor speed controllers on Ebay

Re: Brushed motor speed controllers on Ebay
I use the 20A equivalents in my featherweight, but only with a lot of heavy mods first.
They'd probably be ok in an ant without mods, though they have only 40% power in reverse, and if it's one with a brake then you have to stop at center stick for a second then reverse or it doesn't do anything (don't get one with a brake basicly)
All the attached switch does is turn it on.
They're not ideal in terms of size and firmware, but they do work ok, and are cheap.
I started a thread on the FRA forum about using them in beetleweights if you want some more detail: http://www.fightingrobots.co.uk/threads ... -drive-esc

Re: Brushed motor speed controllers on Ebay
My motto is "If it ain't broke, don't fix it" followed by "if it is broke, bodge it back together and it should be OK"
RONNY actually drives roughly straight now and my driving ability is the limiting factor, currently I don't have any plans for a further improved version...
Maybe I'll get inspired to build a team mate for him
