The HB-25 Motor Controller in a fast and inexpensive way to control a DC motor up to 25 Amps.
The HB-25 motor controller combines the power of a 25 Amp H-bridge with the simplicity of a servo.
The HB-25 is more than just a motor driver chip connected to some logic and high current drivers on a PCB. A quality H-bridge involves an efficient thermal design, which is what the HB-25 has accomplished through a machined heat sink and fan to draw air over the H-bridge; keeping it cool even under full load .
A beautiful piece of engineering and a bargain at the price.
