Find out the differences between the Unipi Neuron and Unipi 1.1 controllers

Unipi Neuron product line, powered by the Raspberry Pi computer, represents compact and powerful controllers suitable for a wide range of automation tasks, from smart home to HVAC (heating, ventilation, air conditioning) control to remote management and monitoring. The Unipi 1.1 is an extension board for the Raspberry Pi computer that allows it to function as an inexpensive and simple controller. That makes it suitable for smaller projects, prototyping or smart home control. 

Note: The number and type of inputs, outputs and communication interfaces available on Neuron controllers differ depending on the specific model - see the input/output table below.
