The PLC Proto Industrial Board is a base module designed for industrial applications in the M5Stack ecosystem. It accepts 9–24 V DC power input and includes a protoboard area for custom circuit layouts, plus an RS485 adapter board with an integrated ACS712 current sensor for monitoring.
Housed in an industrial-grade plastic enclosure with DIN rail slide guide and magnet mounting, this module gives you a flexible platform for building relay controllers, RS485 communication nodes, LoRa gateways, and other industrial automation projects by stacking compatible M5Stack modules.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- DIN
- As a pin label, DIN stands for 'data in', the input through which a device receives serial data from a controller, as found on SPI displays, LED drivers and other serial modules. DIN can also refer to the German standards body of that name, as in a round multi-pin DIN connector or DIN-rail mounting.
- DIN rail
- DIN rail is a standard metal mounting rail used inside industrial electrical cabinets. When a product is DIN rail mountable, it can be clipped neatly alongside power supplies, relays and other automation hardware in a panel.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- LoRa
- LoRa is a long-range, low-power wireless radio technology often used for telemetry, remote sensors and other links that send small amounts of data over long distances. It is distinct from Bluetooth and WiFi, so sharing a connector or pinout with LoRa hardware does not mean a device actually uses LoRa.
- RS485
- RS485 is a robust differential serial communication standard often used in factories, farms and buildings where cables may be long or electrically noisy, and it can link many devices on a single pair of wires. When a product lists RS485, it can communicate with industrial sensors, meters and control equipment over longer distances than typical hobby serial wiring.
