Hardware
Three pieces of hardware assemble a complete automation system. A controller board with six RJ45 ports acts as the brain. Relay modules connect to those ports with a regular patch cable — no breadboard, no solder, no loose wires. Each module mounts on a shared bracket that works for wall or DIN rail.
All enclosures are FDM-printed in PLA, parametric in OpenSCAD, with screw-less push-rivet closure. The product palette is intentionally small: few components, many combinations.
Controller
Control modules
Relay module — 2 channels (v2)
AvailableTwo SRD-05VDC relays, GX12 output.
Two SPDT relays in a printed enclosure, RJ45 in from the main board and a GX12 panel connector for mains power. Push-rivet closure (no screws); rated 10 A @ 250 V AC. Optional LED window with labyrinth-in-Z cap.

Relay module — 4 channels (v2)
AvailableFour relays, two RJ45 pairs, two GX12 outputs.
Same enclosure family as the 2-channel module, scaled to fit the 4-relay PCB. Two RJ45 pairs (two independent loopthroughs) and two GX12 power connectors for separate circuits. Four LED tunnels with anti-light-bleed dividers.

Mounting
Wall bracket
AvailableScrew-mount with universal T-slot.
Compact bracket to screw straight onto a wall or junction box. The top face exposes a T-slot tongue that mates with the anchor slot on the base AND cap of every Xima Domo enclosure — vertical or horizontal mounting as needed.

DIN-rail bracket
Work in progressDIN-35 clip with the same T-slot.
Snap-on bracket for standard DIN-35 (35 × 7.5 mm) rails with a spring-loaded release pawl. Top face exposes the same T-slot as mount-screw — any Xima Domo enclosure mounts on either bracket interchangeably.
