| **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. | **Each I/O circuit board is controlled by its STM32 processor**, which controls inputs and outputs and communicates with the central processing unit (CPU).

| - | Unipi Axon controllers are powered by a **1.2GHz Allwinner H-5 quad-core CPU**. Compared to Neuron series, all Axon models contain internal **8GB eMMC memory**. That makes the Axon more reliable and less sensitive to memory aging. | + | Unipi Axon units are powered by a **1.2GHz Allwinner H-5 quad-core CPU**.
