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.
