3-axes stepper motor controller and driver unit for embedded applications

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 offering 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 1rmware 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 offering advanced features.
