 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** ​use binary logic; that makes them two-state inputs utilizing DC voltage pulses. Axon digital inputs ​are designed for 5-40V DC voltage rangereceiving ​voltage ​pulses from corresponding external devicesTypical examples of such devices are digital lightning ​switches, ​magnetic contacts in windows or doorsmotion ​sensors ​etc. It is also possible to connect pulse meters ​(energy meters, water flow meters ​etc.). +**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 presentno wateretc. The software detects logical 1 (trueif the input voltage between given DIx.y and DIGND is between 5-30VIf the voltage ​is lower than 3.5Vthe state is evaluated ​as 0 (false)
