Stepper 4 click - MikroElektronika Bipolar Stepping Motor Driver
Stepper 4 click - MikroElektronika Bipolar Stepping Motor Driver
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.
| DMODE0 | DMODE1 | DDMODE2 | Function |
|---|---|---|---|
| 0 | 0 | 0 | Standby mode (the OSCM is disabled and the output stage is set to ‘OFF’ status) |
| 0 | 0 | 1 | Full step resolution |
| 0 | 1 | 0 | Half step resolution (Type(B)) |
| 0 | 1 | 1 | Quarter step resolution |
| 1 | 0 | 0 | Half step resolution (Type (B)) |
| 1 | 0 | 1 | 1/8 step resolution |
| 1 | 1 | 0 | 1/16 step resolution |
| 1 | 1 | 1 | 1/32 step resolution |
