1 Features
The TMCM-3230 is a compact three axes 2-phase stepper motor controller and driver module. It provides
a complete motion control solution at a very small size for embedded applications. The board can be
easily plugged into a customized baseboard oering a single 68pin connector.
Host communication is possible via the serial UART interface (e.g. using a standard RS232 or RS485 level
shifter) or via CAN (CAN controller is already integrated on board). An additional USB interface (Micro-USB)
may be used for rmware updates, download of TMCL programs or setting of parameters - either in
system or stand-alone without any further connections.
The TMCM-3230 is supported by the intergated development environment TMCL-IDE v3.0. It supports
stand-alone TMCL program execution (on-board EEPROM) and remote controlled operation.
The TMCM-3230 has been designed with compatibily in mind with previous generation TMCM-343/TMCM-
303 modules - keeping similar mechanical and electrical characteristics (drop-in replacement for many
applications) while oering advanced features.
