SCE2 4-Axis Stepper Motor Controller

SCE2 is a compact, fully integrated 4-axis stepper motor controller module (SOM) that combines an STM32F103 ARM Cortex-M3 microcontroller with Trinamic micro-stepping drivers to drive up to four bipolar stepper motors from a small USB-connected module. It runs an industry-standard G-code interpreter with linear interpolation, making it ready to control motion directly from text commands without external components.

Applications 

SCE2 is suited for small motion systems like compact CNC mills, laser cutters/engravers, pick-and-place machines, robotics, automated test fixtures or other devices where space is limited but precise multi-axis control is needed. It fits in custom devices that require embedded motion control without a large controller board.

Features

  • 4 stepper motor channels with up to 1/256 micro-stepping for smooth, precise motion control.
  • STM32F103 (ARM Cortex-M3) running at 72 MHz with open-source G-code firmware for standard motion commands (linear moves, arcs, homing, etc.).
  • Trinamic drivers with digital current control allowing software-configured motor coil current up to ~1.2A per motor.
  • USB interface for communication and power, registers as a virtual COM port on hosts.
  • Limit switch inputs and multiple GPIOs (some with PWM/timers) for homing and custom signals.
  • Optional serial / TTL UART / I²C connectivity with custom firmware for embedded host integration.
  • Small footprint (~17.5 × 27.5 mm) ideal for integration into compact motion products.
