Raspberry Pi 5 (8 GB)
The default high-level computer for a mid-size robot. Real PCIe, two camera ports, and enough CPU to run ROS 2 nodes, a web dashboard and a modest neural network at once.
The role it plays
Every serious robot needs two tiers. A microcontroller owns the control loop at a fixed rate with hard deadlines, because a missed deadline is a visible jolt. A Linux or GPU board owns perception, planning and networking, because those are bursty and best-effort. Nothing balance-critical belongs on the Linux side.
Typical use: ROS 2 host, vision, web dashboard, data logging.
What the numbers actually mean
The headline figure is 4× Cortex-A76 @ 2.4 GHz (cpu), with 8 GB LPDDR4X as the next most load-bearing number (ram). At $80 in the compute tier it sits in the mid range: enough money that you should plan the mounting and wiring before ordering, but not so much that one mistake ends the project.
How it compares
Same subsystem, closest alternatives. The primary spec column is usually the one that decides it.
