INFO
The TMCM-303 is a compact and versatile triple axis 2-phase
stepper motor controller and driver module. It provides a com-
plete motion control solution at a very small size for embedded
applications. Using the integrated additional I/Os it even can
do complete system control applications. The board can be con-
nected to a baseboard or customized electronics with a pin con-
nector. The TMCM-303 comes with the PC based software devel-
opment environment TMCL-IDE. Using predefined TMCL (Trinamic
Motion Control Language) high level commands like „move to
position“ or „constant rotation“ rapid and fast development of
motion control applications is guaranteed. Host communication
is possible via the serial UART interface (e.g. using a RS-232 or
RS-485 level shifter) or via CAN. All time critical operations, e.g.
ramp calculation are performed on board. A user TMCL program
can be stored in the on board EEPROM for stand-alone opera-
tion. The firmware of the module can be updated via the serial
interface. With the optional stallGuard™ feature it is possible to
detect overload and stall of the motor.
