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. 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 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.
