All about the product
The stepper motor controller is compatible with Arduino, STM32Discovoery, Raspberry Pi. The controller can be configured, tested and monitored via USB, and runs on Windows, Linux and MacOS. To control the stepper motor, connect the system as shown in the picture. If the rated motor voltage is lower than the required power supply of the controller (10 V), the current limit must be set manually using a potentiometer. The board is designed to dissipate heat when the current consumes about 1.8 A per coil. If the current is much higher, an external heat sink must be used, which can be mounted with thermally conductive adhesive.
Technical data:
- Motor supply voltage: 10 V - 47 V
- Current: max. 1.8 A per coil (4.5 A after cooling)
- Controller supply voltage: 5V regulator - no external power supply required
- Simple control interface
- 6 modes: full step, 1/2, 1/4, 1/8, 1/16 and 1/32 step
- Possibility to adjust the motor current consumption with a potentiometer
- Motor overcurrent protection
- Automatic switching between modes based on motor current consumption
- System overheating protection
- 6 control interfaces: USB, serial TTL, I2C, RC pulse servo, analog, quadrature encoder
- Maximum step speed: 50,000 steps per second
- Kit for self-assembly
In the kit:
- Controller TB67S249FTG
