3.2 Connectors
The TMCM-1110 stepRocker has nine connectors altogether. There are two screw connectors for power and
motor and two interface connectors (mini-USB and RS485). Further, the stepRocker has one connector for
reference switches for all three motors, the driver input connector (TTL level) for motor 0, two controller output
connectors (TTL level) for motors 1 and 2 and the GPIO connector, which can be used e.g. for connecting an
ABN-encoder.
Start with power supply OFF and do not disconnect the motor while the board is powered as this can
destroy the transistors!
