Overview

The BB-101 is a base board designed for the TMCM-101 single-axis 2-phase stepper motor controller and driver module. It provides integrated access to motor connections, power supply, and reference switches via screw terminals, alongside industry-standard headers for encoder feedback and 16 general-purpose I/Os. The board includes a switch-mode regulator to generate a 5V supply from an input range of 15V to 28.5V DC. It supports communication via RS-232, RS-485, and CAN interfaces and is compatible with the TMCM-101 module which utilizes the Atmel AT90CAN128 microcontroller and TMC428 motion controller. The board is rated for up to 3A RMS (4.2A peak) coil current and includes StallGuard for sensorless reference search.

Use Cases

  • Fast prototyping of motion control applications with high-current stepper motors
  • Ad-hoc evaluation of the TMCM-101 module
  • Closed-loop stepper motor drive systems
  • Laboratory use for motion control experimentation
