Product information "DC MOTOR 4 click"

DC MOTOR 4 click is capable of driving motors with a supply voltage from 4.5V to 36V. It carries the MAX14870 motor driver from Maxim Integrated. The click is designed to run on either 3.3V or 5V power supply. DC MOTOR 4 click communicates with the target MCU over the following pins on the mikroBUS™ line: PWM, AN, CS, and INT.

The J2 jumper onboard the click is used for selecting a power supply - either the onboard 5V or the external DC motor power supply input.

DC MOTOR 4 click can be used to driving DC motors, controlling the motor's speed, the direction of the rotation, as well to brake and regulate the current.

MAX14870 driver features

The MAX14870 motor driver offers a small, low power solution for driving and controlling brushed DC motors and relays with voltages between 4.5V and 36V.

Very low driver on-resistance reduces power dissipation. It features a charge-pump-less design for reduced external components and low supply current.

How the click works

There are two onboard screw terminals - one is for connecting the DC motor, and the other one is for connecting an external source if necessary. The DC motor is controlled through PWM, CS and AN pin of the click board.

Code examples for DC MOTOR 4 click, written for MikroElektronika hardware and compilers are available on Libstock.

Code snippet

The following code snippet shows the initialization and use of compiler built-in PWM functions to control the motor.

01 void systemInit()
02 {
03     GPIO_Digital_Output(&GPIOA_BASE, _GPIO_PINMASK_4);
04
05    pwmPeriod = PWM_TIM5_Init(1000);                                   // Set PWM frequency/period (according to the DC motor characteristics)
06     PWM_TIM5_Set_Duty(pwmPeriod,  _PWM_NON_INVERTED, _PWM_CHANNEL1);   // Set current duty for PWM
07     PWM_TIM5_Start(_PWM_CHANNEL1, &_GPIO_MODULE_TIM5_CH1_PA0);          // Start PWM
08
09 }
10
11 void main()
12 {
13
14    systemInit();
15
16    while (1)
17     {
18         //Forward
19         DIR_PIN = 0;
20         //Forward fast
21         PWM_TIM5_Set_Duty(pwmPeriod,  _PWM_NON_INVERTED, _PWM_CHANNEL1);
22         Delay_ms (3000);
23         //Forward slow
24         PWM_TIM5_Set_Duty(pwmPeriod/2,  _PWM_NON_INVERTED, _PWM_CHANNEL1);
25         Delay_ms (3000);
26         //Reverse
27         DIR_PIN = 1;
28         //Reverse fast
29         PWM_TIM5_Set_Duty(pwmPeriod,  _PWM_NON_INVERTED, _PWM_CHANNEL1);
30         Delay_ms (3000);
31         //Reverse slow
32         PWM_TIM5_Set_Duty(pwmPeriod/2,  _PWM_NON_INVERTED, _PWM_CHANNEL1);
