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.ApplicationsSCG1-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.Features6 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.Resources Documentation SDK 3D models
SCF4 3-Axis Stepper Motor Controller
SCF4 is a compact, fully integrated 3-axis stepper motor controller System-On-Module (SOM) designed for high-density integration in products where small size, reliability and ease of use are important. It pairs an STM32F103 (ARM Cortex-M3) MCU with an ON Semiconductor LC898201 motor driver front end to drive three bipolar stepper motors (plus an optional day/night IR filter) with micro-stepping up to 1/1024 for quiet, precise motion.ApplicationsSCF4 is ideal for motorized zoom/focus/aperture (FIZ+) lenses in embedded vision systems, robotics and small automation; it’s great for computer vision, scientific imaging, remote or autonomous camera systems, drones/ROVs, long-term timelapse rigs and compact motion products. The module can be connected over USB or, with custom firmware, other bus interfaces to integrate into larger systems.Features3 stepper motor channels with up to 1/1024 micro-stepping for smooth and precise control.STM32F103 MCU runs standard or custom firmware with support for industry-standard G-code commands.Onboard H-bridge for an optional IR/day-night filter mechanism.Limit switch inputs and GPIO/ADC pins for homing and custom signals.Small footprint: ~16 × 23 × 2.3mm module ideal for embedded products.Connectivity: USB (Full-speed 12 Mbit/s) by default; optional USART, I²C or SPI support with custom firmware.Industry-standard G-code command set for motion, status and configuration control.

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.Features4 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.Resources Documentation SDK 3D models
