Building a Raspberry Pi 5 into an industrial control panel typically means cobbling together a display, a case, some thermal management, and a lot of creative cable routing. Argon40 is pitching the Argon Industria HMI 5C as a single solution: an aluminum enclosure that mates the Pi 5 with the official 5-inch Raspberry Pi Touch Display 2 (720 x 1280) to produce a compact, panel-mountable Human Machine Interface ready for automation dashboards, kiosk applications, or embedded control systems.
The enclosure's most notable engineering detail is its passive cooling approach. A metal column contacts the Pi 5's SoC and conducts heat directly into the thick aluminum chassis, effectively turning the entire case into a fanless heatsink. That column does occupy the HAT header space, so users who want to attach expansion boards like the Cytron Industrial IO HAT+ will need to remove it and switch to a low-profile active cooler instead. An internal IO daughterboard reroutes all of the Pi 5's ports, including converting both micro-HDMI outputs to a single full-size HDMI connector, and consolidates USB, Gigabit Ethernet, GPIO, and USB-C power along one edge of the enclosure for cleaner cable management. Argon40 notes the daughterboard is compatible with adapters that add an M.2 2230/2242 NVMe slot via the Pi 5's PCIe interface, opening up fast local storage.
Mounting options cover VESA, panel cutout, and desktop placement, with a soft foam gasket sealing the display bezel. Argon40 also says the enclosure will support upcoming Argon Industrial Communication modules for connecting to broader automation networks. The HMI 5C enclosure alone is $35 (€32), while a complete kit bundling the case, a Raspberry Pi 5 with 16 GB of RAM, the 5-inch touch display, and the Cytron IO HAT+ runs $511 (€470). A case-plus-display bundle without the Pi board is available for $93.25 (€86). For those with the larger 7-inch Pi Touch Display 2, Argon40 offers the HMI 7C variant as well.
