Stepper 4 click

PID: MIKROE-2748



Stepper 4 click can be used for driving a stepper motor and controlling its step resolution,

rotation direction, and time between the steps. It has output drive capability of 2A.

Stepper 4 click carries the TB67S269FTG, a two-phase bipolar stepping motor driver from

Toshiba. The click is designed to run on either 3.3V or 5V power supply. It communicates with

the target microcontroller over the following pins on the mikroBUS™ line: AN, RST, CS, PWM,

INT.

Howtheclickworks

There is a connector with two screw terminals used for connecting external DC supply.

The other four connectors are used for connecting the stepper motor to the click. After a motor is

connected, it can be controlled by the MCU through the Stepper 4 click.

The onboard potentiometer is used to set the motor's torque.

TB67S269FTGfeatures

The TB67S269 is a two-phase bipolar stepping motor driver from Toshiba.

Stepmodeselector

There are several different resolutions a stepper motor can use - a full step, half a step, etc. The

driver on this click also allows different resolutions, from a full step to 1/32 of a step.

Codesnippet

The following code snippet shows how the Stepper 4 click moves a stepper motor.

Firstly, the speed is set to 400 steps per revolution. Afterwards, the acceleration and the

deceleration rate is set. The STEPPER_step method moves the motor a given number of steps.

When the number is negative, the motor moves counterclockwise, otherwise, it moves clockwise.

So in this example, it first moves 1000 steps to the left, and then 1000 to the right, at different

speeds.
