 +Depending on the model, Neuron controllers feature 1-3 sections. See [[#​sizes_and_sections|below]] for more info.
  
-Each Neuron model is divided into one to three input-output (I/O) groups depending on model, each containing a group of inputoutput ​and/or communication modules. The Neuron can contain 1 (S-series), 2 (M-series) or 3 (L-series) I/O groups+**Each I/O circuit board is controlled by its STM32 processor**which controls inputs ​and outputs and communicates with the central processing unit (CPU). Processors are using custom firmware containing not only basic I/O functions but also additional functions and features.

-===== CPU ===== 
  
-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**.+==== CPU ====
  
-{{:en:hw:​01-products:​01-neuron:​neuronexplanation_2x_1_.png?​direct&​600|UniPi Neuron internal topology}}+Standard Neuron models are using an integrated Raspberry Pi 3 Model B as a computing module. The [[https://​www.unipi.technology/​unipi-neuron-s103-raspberry-pi-4-p364|S103 (Raspberry Pi 4)]] features an integrated Raspberry Pi 4 Model B. The following table compares the technical parameters of both options: ​

-Along with basic I/O features this product offer additional unique featureseither improving its performance or making it ready for cases of emergency.+
  
-=== Direct Switch === +<WRAP center round important 95%> 
-Direct switch allows you to set appropriate device reaction based on input signal without a need of master control unit (Raspberry Pi computer build inside ​Neuron ​controller). This function is great for real-time applicationsIt also comes in handy in case of malfunction of the master control unit.+**HDMI port on Unipi Neuron ​controllers** is intentionally sealed, as using the graphic chip can cause system instability (issues with the used software or overheating). Some HDMI displays can damage the controller just by connecting to it (egdue to the ground potential difference). **Removing the HDMI seal renders the controller'​s warranty null and void**
  
-=== Default configuration === +<​html><​span class="​avOrangeText">​As a solution, you can use external displays: </​span></​html>​ \\ 
-It is possible to store default settings inside the module memory and when the device rebootsit configures itself according to stored default settings.+  - HMI -> Weintek 
 +  - Web interface -> smartphone/​tabletPC, atd.
 +</​WRAP>​
  
-=== Master Watchdog === 
-This function periodically controls communication with the master control unit (Raspberry Pi computer). If for a period predetermined by a user there is no communication with the master unit, it will load and set the stored default settings. Your applications will function even in emergency cases. 
  
-===== Communication interfaces ====== 
  
-By standard, all Neuron models feature up to **three RS485 serial lines** for connecting of external devices or extension modules (i.e. [[en:​hw:​04-extensions|Extensions]]). One line can communicate with up to 32 devices, using the Modbus RTU protocol. ​+==== Communication interfaces ====

 +By default, all Neuron models feature up to **three RS485 serial lines** for connecting of external devices or extension modules (i.e. [[en:​hw:​04-extensions|Extensions]]). One line can communicate with up to 32 devices, using the Modbus RTU protocol. ​ 
 + 
 +Each Neuron also features a **single 1-Wire bus** for the passive reading of data from corresponding 1-Wire sensors (humidity sensors, temperature sensors etc.). One bus can receive data from up to 15 sensors at once (provided a suitable 1-Wire hub is used).  
 + 
 +As the Unipi Neuron product line is based on the Raspberry Pi, all Neuron controllers feature **up to 4 USB ports**. These ports can be used for connecting various USB convertors, external memory drives etc. We do not recommend using them to power external devices.
