The PLC M12 V1.1 is a base designed for industrial application with a DC Power in 9-24V. Does this PLC remind you of the 'PLC' in industrial control short for 'Programmable Logic Controller'? This PLC base is not the typical 'PLC' used in programmable controllers, but it does enable you to implement the most common controller in the industrial field. Based on the current M5 development system, you can add as many relays as you want, you can enable the TTL-RS485 communication and can lay out your customized circuit on the protoboard. You also can make it a LoRa node by stacking a LoRa module etc. This base gives you an unlimited number of combinations. It is powerful, flexible, and has an industrial-grade case. If you work in an industrial field, we especially recommend this PLC base, which will help with any kind of project you have in mind.
If you need to add the RS485 interface, solder the RS485 board onto the mean board pin correspondingly. The serial port pins on the RS485 board will be connected to the GPIO16 and GPIO17 of the PLC backplane.
