4.3 Input/output circuits
4.3.1 Hall sensor input
The hall sensor input circuit supports +5V push-pull (TTL) and open-collector hall sensor signals. In order to
support open-collector signals the input circuit offers 2k7 pull-up resistors to +5V (generated on-board from
power supply voltage).

4.3.2 Encoder input
The encoder input circuit supports +5V push-pull (TTL) and open-collector hall sensor signals. In order to
support open-collector signals the input circuit offers 2k7 pull-up resistors to +5V (+5V generated on-board
from power supply voltage).
