Problems with SD-21
January 3, 2011
Hi guys, does anyone out there have experience with the Rev-Ed SD-21 servo controller?
Mine's malfunctioning in a wierd way - I'm running 4 servos with it, and the one on output 1 is juddering all over the place while the others are fine. It's not the servo, that works fine in the other outputs.
All the servos attached to the bot jump about in the same way when they're plugged into 1, but any servo that's not attached works fine. The bot's made of aluminium, but it can't be electrical noise from that because nothing's connected to it...
