6.4 Receive (Rx) Channels

There are five RX input pins to be connected to receiving electrodes. Every pin feeds a dedicated ADC.

To simplify layout, the association between logical electrodes (e.g. “West”, “East”, etc…) and physical pin (RX0…RX4) can be freely performed in software.
Note: When only four electrodes are required in the application, it is recommend to use RX channels RX1…RX4, while RX0 can be left disconnected.
