Andino IO - Raspberry Pi on DIN Rail

The Andino IO is a microcontroller board for the Raspberry Pi in a DIN-rail housing for installation in a control cabinet. It is used to adapt digital inputs and outputs for a voltage of 24 V. It also contains a Raspberry Pi. The inputs and outputs as well as the power supply of the Pi are optimally protected. Communication between the microcontroller and the Pi takes place via the UART interface.

For a general introduction on the Andino IO board, see Andino IO

The LoraWAN modem is connected to the UART RS232-WAN extension as descibed in Dual Channel UART RS232-WAN Extension.
