NOTICE

Do not connect or disconnect motor during operation!

Motor cable and mo-

tor inductivity might lead to voltage spikes when the motor is (dis)connected

while energized. These voltage spikes might exceed voltage limits of the driver

MOSFETs and might permanently damage them. Therefore, always switch oﬀ

/ disconnect power supply or at least disable driver stage before connecting /

disconnecting motor.

NOTICE

Take care of polarity, wrong polarity can destroy the board!

4.2 I/O Connector (Microcontroller)

The TMCM-1110_V23 oﬀers an on-board ARM Cortex-M4

™

microcontroller with +3V3 powered IOs and

+5V tolerant inputs. In order to be compatible with previous generations of the module, +5V output

level-shifters/buﬀers have been integrated on-board. This way, all general purpose IO pins conﬁgured as

outputs will deliver +5V TTL signals.
