3D Printer Extruder Breakout Board, CAN USB for

【CAN USB Connectivity】The extruder board supports CAN bus and USB communication to simplify 3D printer wiring, reducing cable clutter, while the BOOT button allows for convenient firmware updates via USB DFU mode.
【Performance】A built-in MEMS accelerometer fine-tunes movements for sharper layers and more precise prints, while the I2C interface detects filament breakage or jamming for improved tracking.
【NEMA 14 Motor】Designed for NEMA 14 (42mm) stepper motors, this extruder board ensures stable installation in compact print heads, with shielded cables and wires suitable for cable carriers to reduce electromagnetic interference.
【Circuit Protection】Provides ESD protection on exposed motor and I/O ports, as well as protection against overheating. Short circuits on data inputs, I/O pins, and thermistor interfaces protect the printer electronics during operation. [Complete Installation Kit] Includes terminal blocks, female pins, standoffs, and screws for flexible custom assembly. Withstands ambient temperatures up to 75°C in enclosed printers; refer to the pinout diagram to avoid reverse polarity or CAN errors.
