This nifty manual speed controller keeps it basic and functional! Convenient terminal blocks allow connection of power input and motor out while the knob on the front of the board allows you to control speed between 0% and 100%. A heatsink has been attached to the control circuitry to keep things reasonably cool even at full load.

We tested this with our resistive load simulator at 12VDC and it was able to coolly drive up to 2.4A through the load before clamping the output. As this is an inductive motor driver, perhaps it responds better to a true motor instead of a programmable load simulator.

Please be aware that this is not a reversing motor controller. It's a simple, 1-direction DC motor driver.

Note: Product not exactly as shown. Module has been upgraded with a metallic knob and larger heat-sink for better power-dissipation.
