Description

Module one-channel H bridge VNH3SP30 ST lets you control the motors with a supply voltage in range 5.5 V - 24 V continuous drain current up to 12 A, for short periods up to 30 A. the System allows you to change the motor rotation direction and speed control through a PWM signal.

Insights

 

 

The minimum number of connections of the module VNH5019 with a microcontroller.

The input PWM signal pulled up to the masses. The power outputs of the engines, so they are blocked by default. On the Findings of controlling the direction of rotation INA, MOS was not installed by default, no potential.

 

The LEDs located on the Board, they are very useful for discovering problems with the connection. The brightness increases with the rotational speed of the engine, and the color changes with the direction of rotation.
