 Each Neuron model is divided into one to three input-output (I/O) groups depending on model, each containing a group of input, output and/or communication modules. The Neuron can contain 1 (S-series), 2 (M-series) or 3 (L-series) I/O groups. ​ Each Neuron model is divided into one to three input-output (I/O) groups depending on model, each containing a group of input, output and/or communication modules.

 All Neuron models are using the **Raspberry Pi 3 Model B** as its central processing unit. Each I/O group is connected to the CPU and to a central communication channel for all group processors. There is no communication between I/O groups. **Each processor can also function independently on the CPU, allowing users to retain basic control of I/O modules in the event of CPU malfunction or software issue**. All Neuron models are using the **Raspberry Pi 3 Model B** as its central processing unit.

 **Digital inputs (DI)** are designed for reading logical states (true or false), which are represented by levels of DC voltage. That makes them suitable for reading two-state sensors such as switches (on/off), movement sensors (movement/​no movement), water level sensors (water present, no water) etc. The software detects logical 1 (true) if the input voltage between given DIx.y and DIGND is between 5-30V. If the voltage is lower than 3.5V, the state is evaluated as 0 (false) **Digital inputs (DI)** are designed for reading logical states (true or false), which are represented by levels of DC voltage.

-**Digital outputs (DO)** are used for controlling two-state devices such as lights, door locks, window blinds etc. Digital outputs on our controllers also feature the PWM (Pulse-width modulation) function, enabling a special type of analog ​control. Outputs are of the NPN type (open collector) and are able to control devices with voltage up to 50V and up to 750mA load current.+**Digital outputs (DO)** are used for controlling two-state devices such as lights, door locks, window blinds etc. Digital outputs on our controllers also feature the PWM (Pulse-width modulation) function, enabling a special type of analogue ​control.

 **Relay outputs** are used for control or switching of devices with higher current loads. ROs are thus suitable for controlling light bulbs, thermoelectric valve drives, water heaters, pumps etc. Relay outputs on UniPi controllers are rated for 5A max. current at 230V AC/30V DC voltage. **Relay outputs** are used for control or switching of devices with higher current loads.

 **Analogue inputs** (AI) can be used for 0-10V DC voltage or 0-20mA current measuring, making them suitable for reading values from analogue sensors such as temperature sensors, pressure meters, tensometers etc. On some controllers,​ two types of AI are available; the first type can be used to measure current or voltage while the second type additionally supports resistance measuring **Analogue inputs** (AI) can be used for 0-10V DC voltage or 0-20mA current measuring, making them suitable for reading values from analogue sensors such as temperature sensors, pressure meters, tensometers etc. On some controllers,​ two types of AI are available; the first type can be used to measure current or voltage while the second type additionally supports resistance measuring
