01What makes a Pi “industrial”
The chip is the same; the engineering around it is not. An industrial Pi trades the SD card and bare GPIO for components and protection that survive a panel.
- 35 mm DIN-rail enclosure, not a desktop case
- Wide-temperature components and conformal coating
- Optically-isolated 24 V digital I/O and protected analog inputs
- Hardware watchdog and brown-out protection
- Industrial eMMC instead of a wear-prone SD card
- 9–28 V DC input with surge/EMC protection
- EN 61131-2 compliance and a guaranteed lifecycle
02The platforms worth knowing
Revolution Pi (KUNBUS) is the most established and the most certified, with modular I/O expansion. Seeed's EdgeBox/reComputer line leans into edge AI with Hailo accelerators. Sfera Labs builds compact, well-isolated units. OnLogic ships rugged fanless boxes. And our own Node boards undercut the field by making the hardware ourselves.
03How to choose
Match the board to four things: how harsh the environment is, how much isolated I/O you need, whether you need on-device AI, and what lifecycle guarantee the project demands. Over-specify the environment and you waste money; under-specify it and you're back in the panel in a year.
Common questions
The ones we're asked on every first call.
Yes, when it's the right board. EN 61131-2 platforms with industrial eMMC, a hardware watchdog and isolated I/O are a different class from a consumer Pi on an SD card. Reliability is an engineering decision, not a chip limitation — and the CM5 is guaranteed in production to at least 2036.
It's real on consumer Pis and solved on industrial ones, which use soldered industrial eMMC with wear-levelling and often a read-only root filesystem. We also ship signed, read-only rootfs images so the storage isn't being written on every cycle.
