Reply to "ERR mini commander in a Williams SCALE 44 tonner"

The CC-Lite is out of production, when they were introduced, I ordered a dozen.  I actually did some beta testing of the CC-Lite before they hit the market, so I knew what was coming.  I've used most of them in various projects.  I recently bought two on the for-sale forum, one was toasted, the other was still in the bag.  I repaired the toasted one, so I have a few waiting for my next small engine project.

I think Scott said that there wasn't enough demand for the CC-Lite to justify a run, I suspect he has to order in significant quantities to meet his price targets.  As a guy that uses off-shore electronics assembly, I can tell you that larger quantities translate to much cheaper assembly and component costs.  I'd love to see the CC-Lite come back, but until that happens, I'm jealously guarding my small stock of them for future projects.

One thing about the CC-Lite is it's not nearly as forgiving of overloads, if you have a motor stall with the CC-Lite, it can quite quickly toast the FET motor drivers.  If you aren't really quick, it will also wreck the board making repair impossible.  I'm going to fit a small heatsink to my remaining CC-Lite boards with thermal epoxy to give myself a little headroom.  I also install a PTC in series with the motor on any CC-Lite installation I do.  That's also a good idea with the Mini Commander II if you use them for motorized units.

A mini Commander might fit but its only rated for two amps. Stall current on those motors in parallel is greater than 5 amps. Even if you wired the motors in series you would be pushing the limit of the mini.

 That's what the PTC is for, you are correct, it's a real issue.  I cooked one of my beta test CC-Lite boards that very way.

 Do you distribute ERR items as well?

 Sure do, if you need something, let me know.
