 ==== Low-pass filter ====
-Low-pass filter can be composed between external analogous inputs 0-3 (PF0-PF3). Resistor and capacitor will be connected to the socket for building up the low-pass filter. By default a low-pass filter is composed for the channel 0 (PF0). Resistor value is 10 kΩ and capacitor value is 100 nF.

 ==== Digital I/O connector ====
-In addition to sensors and analog inputs, there is a connector for digital I/O on the board. The pins of the connector are directly connected to pins PE2-PE5 of the controller.
