HIGH QUALITY TO BE TRUSTWORTHY:
1. Low Power Supply Voltage (Dc 2-9v), Most Suitable for Battery Powered Products. 3.3v or 5v Microcontrollers Can Be Easily Controlled.
2. Low Resistance Output, Even at High Current Output, the Chip Temperature Will Not Be Too High;
3. the Input Signal Voltage Has a Wide Range of 2-9v;
4. Powerful Protection Functions, Such As Overcurrent Protection and Overheating Protection, All Achieve Protection by Limiting the Driving Current. This Protection Method Is Very Suitable for Driving Dc Motors Because the Starting Current of Dc Motors Is Very Large. This Protection Can Ensure That the Motor Starts Normally Without Burning the Drive Chip. Even If You Connect a 100w Motor, Although the Drive Board Cannot Move the Motor, It Will Not Burn out the Drive Chip, so You Can Confidently Connect Any Dc Motor for Experimentation;
5. the Input Pwm Signal Is Used for Speed Regulation, and It Is Generally Recommended to Use a Pwm Signal of Around 16khz. If Only the Motor Needs to Start and Stop, Connect to a High-level Start and a Low-level Stop. High Level 2-9v Can Be Used, While Low Level Can Be Suspended or Grounded.
6. Forward and Reverse Input Low Level Forward Rotation, High Level Reverse. High Level 2-9v, Low Level Suspended or Grounded.
7. Output Current 1a, Maximum Peak 3.2a.
Attention:
There Is No Voltage Reverse Protection on This Board, so Be Sure to Pay Attention to the Positive and Negative Poles of the Voltage When Connecting to the Power Supply.
The Input Ground and Power Ground Are Connected Together in the Circuit Board.
