FAQs:
Q: What types of motors can the Raspberry Pi Expansion Board control?
A: The expansion board can control both DC motors and stepper motors. It provides the necessary drivers and PWM control for precise operation of these motors in various projects.
Q: How many DC motors and stepper motors can the board drive simultaneously?
A: The board can drive up to 2 DC motors and 1 stepper motor simultaneously. It features two H-Bridge motor drivers for DC motors and one stepper motor driver for precise control.
Q: What are the main features of the Raspberry Pi Expansion Board?
A: The board includes drivers for DC and stepper motors, supports PWM for speed and direction control, and provides connectors for easy wiring. It is designed for robotics, automation, and control projects.
Q: What power supply is required for the Raspberry Pi Expansion Board?
A: The expansion board requires an external power supply for the motors. The supply should match the voltage and current specifications of the motors being used, with a recommended range of 5V to 12V.
Q: How do I connect the Raspberry Pi Expansion Board to my Raspberry Pi?
A: The board connects to the Raspberry Pi via the GPIO pins. It features a GPIO header that plugs directly into the Raspberry Pi’s GPIO header, providing access to control signals and power.
