Description
Interface Description:
1. VM: The power supply of the drive module is input according to the parameters of the motor, and the measured range is 7.6~40V
2. VCC: Connect to 5V input, do not input 3.3V, otherwise it will affect the performance
3. GND: is the ground pin
Control example (when the above 3 pins are connected):
Task 1: A motor rotates forward, duty cycle 50%
Solution: The two wires of motor A are connected to AOUT1 and AOUT2 respectively, AIN1 is connected to low level, and AIN2 is connected to 50% PWMO
Task 2: B motor reverse, duty cycle 20%
Solution: The two lines of motor B are connected to high level according to BOUTL BOUT2o BINI respectively, and BIN2 is connected to 20% PWM
(If your PWM frequency is relatively high, such as 10KHZ, you need 2 PWM pins to control the forward and reverse rotation. If you use Arduin's default frequency of 500Hz PWM. You can use a 10 and a PWM pin to control the forward and reverse rotation, But the effect is not as good as 2 PWM pins)
Parameters:
Function: It can control the forward and reverse rotation of 2 motors (for example, the balance car only
requires one of this module)
Voltage: 7.6~40V
Current: The module has current limit protection, 2A (overcurrent will not power off, only limit the maximum output current
Control: 4 PWM pins are required, (if inversion is not required, only 2 PWM pins are required) it is much simpler to use than 298
Weight: 3g
Size: 23*18.3MM
Lead out: 2 rows of 7pin pin headers
Spacing: 20MM
Package includes:
1 x Motor Driver Board
