Stepper Motor Servo Robot Expansion Board for Raspberry Pi
Elevate your robotics projects with this versatile expansion board for Raspberry Pi. Designed for seamless integration, it allows you to control up to four DC motors, two stepper motors, or four servos using just the I2C bus, preserving your Raspberry Pi's GPIO pins. The board features a dedicated PWM driver for precise speed control and an integrated infrared receiver for convenient remote operation. Power your motors with an external supply (5V-12V) and leverage the stackable design to connect up to 16 shields for complex robotic systems.

What customers say
Consumers consistently highlight the excellent value this expansion board provides for building complex robotics projects. The hardware itself is robust and reliably drives both stepper motors and servos. However, the learning curve associated with the software libraries and initial configuration is a recurring theme. While the board delivers powerful functionality once integrated, users note that achieving seamless operation requires patience and often external community support beyond the provided documentation. Despite the setup challenges, the low cost relative to its capabilities makes it a highly attractive and worthwhile investment for dedicated hobbyists.
