Why we recommend it

Reach for a Raspberry Pi when the arm needs to think rather than just move: running OpenCV on a camera feed, hosting a web control panel, running ROS 2, or doing inverse kinematics in Python. The Pi 5's quad-core processor and 8GB of RAM handle real-time vision far more comfortably than older boards, and its 40-pin header talks to a PCA9685 servo driver over I2C. Linux is not a real-time system, so the common pattern is to let the Pi decide where to go and let a PCA9685 or a small microcontroller generate the servo pulses. This listing is the bare board: budget for a 27W USB-C power supply, a microSD card and an active cooler, which the Pi 5 needs under sustained load.

At a glance

RAM	8GB
CPU	Quad-core Arm Cortex-A76
GPIO	40-pin header (I2C, PWM, SPI)
Camera	2× MIPI camera/display connectors
Note	Board only — PSU, microSD, cooler sold separately
