This DC Motor Speed Controller is a Low voltage motor speed controller for compact dc motors.
Works great with our 3V dc motors.
NOTE: Pre-assembled. Not A Kit!
Maximum Input Voltage: 8V dc
Nominal Input Voltage: 3-6V dc (Higher input voltage (<8V) increases motors torque.)
Maximum Output Voltage: 3V dc
Nominal Output Current: 100 mA
Variable Speed with ON/Off Switch
Speed depends on motors rated RPM
Approx. 35% motors rating: Slow Speed
Approx. 85% motors rating: Fast Speed
Based on a KA2402 motor speed controller IC current mirror and comparator circuit.
Output is through a 2SC2328AY Power Transistor.

LED connection for 0n/Off indicator, not required for controller to work.
Lead Length: ~5"
