1 Features

TMCM-1070 is an easy to use stepper driver unit with state of the art feature set. It is highly integrated

and oﬀers a convenient handling. TMCM-1070 can be used with a simple step and direction interface and

can be conﬁgured using a TTL UART interface. stallGuard2 and coolStep can be conﬁgured via TTL UART

interface and are disabled by default.

1.1 General Features

Main Characteristics
