Our single-board computer catalog tracks 815 boards and compatible accessories: Raspberry Pi 5 / Zero 2 W / Compute Module 5, Orange Pi 5 Plus, Rock 5B, LattePanda Sigma (Intel Core i5 SBC), BeagleBone AI-64, and Banana Pi M5. Match the board to the mission: Raspberry Pi 4 / Pi 5 are the default for Pi-hole (network-wide ad blocking), home Plex / Jellyfin servers, PiKVM (network KVM over IP), and low-power Docker homelabs — the Pi 5 adds PCIe Gen 2 via the M.2 HAT+ for NVMe-speed storage. Orange Pi 5 Plus (RK3588, up to 16 GB LPDDR5, 2.5 GbE, HDMI-in) and Rock 5B offer more raw compute per dollar for compile farms, self-hosted CI, and GPU-less AI inference. LattePanda Sigma runs full x86 Windows 11 or Linux on a credit-card board — useful when the workload needs x86-only software. For local AI inference at the edge, pair a Pi 5 or Rock 5B with a Coral USB Accelerator or M.2 Hailo-8L (up to 26 TOPS int8, stays under 3 W). Filter listings by RAM tier (2 GB / 4 GB / 8 GB / 16 GB), connectivity (GbE vs 2.5 GbE, PCIe M.2 slot, USB 3.0 count), and GPIO count when the build needs hardware I/O.
