Single Board Computers (SBCs)
This section is for SBC guides where the specific hardware platform and its physical placement matter.
Unlike VMs in Proxmox, an SBC is a physical appliance. It has independent power, dedicated networking, and specific hardware traits (like native PCIe, SATA, or PoE) that dictate its role in the homelab.
Because the physical boards are frequently repurposed, these deployment guides are anchored to the specific hardware nodes currently active in the infrastructure.
Hardware Nodes
- Radxa Rock 5B - The Heavy Lifter (Observability Bastion & Prometheus Hub).
- Banana Pi BPI-M2 Ultra - The Storage Node (Dedicated Config Vault & Light NAS).
- Raspberry Pi 4B - High-Availability DNS (Pi-hole) and Proxmox Quorum Device.
- Banana Pi M2 Pro - The Air-Gap Bypass (Physical Subnet Router).
- Raspberry Pi 3 - The Experimental Swarm (K3s/Docker Swarm Sandbox) & Off-Site Backups.
Dedicated Deployment Guides
- JetKVM Admin Terminal On Raspberry Pi 3 - turn a Pi 3 into a browser-first admin terminal.
