1.5 Interfaces / Extension ports
The NIBObee has 5 extension ports. Each of these ports has four contacts:
plus, minus and 2 signal bits. The port X2 and the port X3 are located near to
the small hole raster fields, where additional sensors e.g. photo-sensitive
resistors or temperature sensors can be contacted.
All ports have additional functions:
Port Signal 1 Signal 2 Information
X1 analog / digital analog / digital Two analog inputs
X2 analog / digital digital Analog input
X3 analog / digital digital Analog input
X4 SCL / digital SDA / digital I²C-interface
