Recently I posted a post on the forum about controlling a larger amount of servos (18). A few people suggested the SD20 servo driver chip which looked awesome so I went ahead and purchased a few of these chips. I have made the board and setup my picaxe 40x2 to send out the commands via i2c however I have ran into some problems that I just can't work out. All of the servos do seem to move to the given position but they seem to lack greatly in power. Second problem is that the servo movement range is greatly decreased.
