This unit is design to run up to 3 low cost hobbyist type servos over a 1-wire network using direct 1-wire control from a single board. Servo's are powered independly of the board (DC power jack provided)and are optically isolated from the 1-wire network, thus keeping servo motor noise off the 1-wire network. It is suitable for many low speed servo applications such as camera control (maybe Camera Pan, Tilt, Focus) or servo controlled sensors where the need is not for high speed control or step resolution but for easy integration into existing 1-wire networks. For many application the 256 step resolution of the DP3-Servo Controller is sufficient and there is no need for high frequency updates of the servo position, which makes this board a candidate for those applications.
