Sterownik silników DRV8833 DC krokowego moduł PWM 1.5A do Arduino CNC

Product description

The DRV8833 module is a dual-channel motor driver for DC motors or a single stepper motor, based on Texas Instruments’ chip. It lets you precisely control direction and rotational speed from a microcontroller. Thanks to its compact size and wide voltage range, this module is an excellent choice for electronics projects. The module is intended for use with ESP8266, with ESP32, with Arduino, and with Raspberry Pi.

The driver includes integrated protection against overheating, short circuits, and overload. It supports motor control using PWM modulation. Unlike older devices, it operates at low voltage and does not require an extra heatsink.

Key specifications

• Motor supply voltage: 2.7V - 10.8V
• Logic voltage: 2.7V - 5.5V
• Maximum continuous current per channel: 1.5A
• Peak current: up to 2A (short duration)
• Supported motors: 2x DC motor or 1x stepper motor (bipolar)
• Module dimensions: approx. 25 x 19 mm
• Connector type: pin header (soldered)

Benefits

• Compact design suitable for small devices without needing a heatsink.
• Built-in protection against overtemperature and overcurrent to protect the circuit.
• Low operating voltage allowing power from single cells or battery holders.
