The SPARKmini Motor Controller is an inexpensive in-line brushed DC motor controller designed to offer the same performance characteristics as the Control Hub (REV-31-1595) or Expansion Hub (REV-31-1153) motor ports in a small 60mm x 22mm footprint. The SPARKmini has three integrated wires with connectors dedicated to power, control, and the motor; one XT30 connector for power, one 3-wire servo-PWM connector for control, and one JST-VH connector for the motor. The figure below shows each of these connections: The Control Hub and Expansion Hub can each drive up to four DC brushed motors. As mechanisms are added to the robot the number of motor ports may not be sufficient. There are two ways to add more motors to the Control System, either the SPARKmini Motor Controller or adding an Expansion Hub. The following two rules give a general idea of when to choose one method over another: If one or two motors are needed, consider using the SPARKmini Motor Controller If three to four additional motors are needed, consider adding an Expansion Hub Features Integrated wires with connectors Brake/coast switch Status LED Specifications Input Voltage (nominal): 12V Operating Voltage Range: 6V-20V Absolute Maximum Voltage: 25V Continuous Current: 15A Peak Current: 20A Input Pulse Width Range: 500μs - 2500μs Input frequency (nominal): 50Hz Output Frequency: 10kHz Dimensions: 60mm x 22mm x 12mm Weight: 0.87oz Power Input Connection: XT30 Male Connector 18AWG 2-conductor wire Signal Input Connection: 1 x 3 Female Servo Connector 22 AWG 3-conductor wire Motor Output Connection: JST VH Connector 18AWG 2-conductor wire Motor Wires Length: 150mm (5.91in) 18AWG Power Wires Length: 300mm (11.81in) 18AWG Control Wires Length: 300mm (11.81in) 22AWG Documentation SPARKmini Motor Controller Guide Adding More Motors LED Status Codes CAD & Drawings REV-31-1230 STEP File REV-31-1230 Drawing
