DC Motor 4 Click Board™
Product Code: MIKROE-2221
The DC Motor 4 Click Board™ is capable of driving motors with a supply voltage from 4.5V to36V. It carries the MAX14870 motor driver from Maxim Integrated. The click is designed to run on either a 3.3V or 5V power supply. The DC Motor 4 Click Board™ 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. The DC Motor 4 Click Board™ 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 Does The DC Motor 4 Click Board™ Work?
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.
