IBT 2 BTS7960 H-Bridge Motor Driver Features:

• 5V isolate with MCU, and effectively protect MCU; 5V power indicator on board.
• Voltage indication of motor driver output end; can solder heat sink.
• Just need four lines from MCU to driver module (GND. 5V. PWM1. PWM2); isolation chip 5 V power supply (can share with MCU 5 V).en.wikipedia.org
• Able to reverse the motor forward, two PWM input frequency up to 25kHZ; two heat flow passing through an error signal output.
• Isolate chip 5V power supply (can be shared with the MCU 5V), can also use the on-board 5V supply; the supply voltage 5.5V to 27V.
• A H-bridge is an electronic circuit that switches the polarity of a voltage apply to a load. These circuits are often use in robotics and other applications to allow DC motors to run forwards or backwards.^[1] The name is derived from its common schematic diagram representation, with four switching elements configure as the branches of a letter “H” and the load connect as the cross-bar.Most DC-to-AC converters (power inverters), most AC/AC converters, the DC-to-DC push–pull converter, isolate DC-to-DC converter^[2] most motor controllers, and many other kinds of power electronics use H bridges. In particular, a bipolar stepper motor is almost always driven by a motor controller containing two H bridges.
