These documents are for the 42+ I/O’s option available for the M‑Duino PLCs. A datasheet and a user guide are provided for each of the base configuration Ethernet option, the GPRS / GSM option, and the WiFi & Bluetooth Low Energy (BLE) option. The datasheet shows the pinouts, the available communications and I/O options, basic start-up, precautions, and contact info. The user guides help you understand the layout of the modules, and provide the details of how to set the switches, hook up the wires, program the controller, etc.

NOTE: The 42+ I/O’s option is also available for the Raspberry PLCs (and soon to be released ESP32 series). The details between the three PLC series differ somewhat; for the Raspberry and ESP32 PLCs, use these documents for reference only.
