SCG1 6-Axis Stepper Motor Controller

SCG1-M is a fully integrated 6-axis stepper motor controller module (SOM) built for compact motion systems that need multiple motor channels, high performance and a small footprint. It runs an open-source G-code interpreter with linear interpolation control on a 32-bit ARM-Cortex M3 microcontroller (72 MHz) and includes Trinamic micro-stepping drivers for fine motion performance.

Applications

SCG1-M excels in motorized zoom/focus/iris (FIZ+) lens assemblies, multi-axis robotics, small CNC machines, laser cutters/engravers, pick-and-place systems, automated test fixtures and other devices where up to six bipolar stepper motors must be controlled precisely within a limited space.

Features

  • 6 stepper motor channels with up to 1/256 micro-stepping for smooth, precise motion control.
  • 32-bit ARM-Cortex M3 MCU (72 MHz) running industry-standard G-code motion firmware.
  • Trinamic driver front end with digital current control adjustable via G-code.
  • Small, fully integrated module requiring no external components.
  • Connectivity: USB port for power and control, plus optional TTL USART/I²C and multiple GPIOs (some with hardware PWM).
  • Limit switch inputs and expansion I/O for homing and system signals. TODO: TBD (specific count and pinout).
  • Dimensions: Slightly larger than SCE2, optimized for multi-axis systems. TODO: TBD exact size.
  • Firmware supports standard motion commands, homing and coordinate moves via G-code.
