STMicroelectronics EVALSP820-XS motor driver board will STMicroelectronics industrial control expertise to fully apply RAMPS (RepRap Arduino Mega Pololu Shield) open source 3D printer platform for 3D printer manufacturers to tap the full potential of the printer, print speed and improve surface Finish.
The RAMPS modular platform is reducing the barriers to 3D printed fuse manufacturing (FFF) technology, enabling equipment manufacturers, small businesses and home users to quickly develop prototypes, manufacture parts, or assist in teaching. The Arduino Mega 2560 or Arduino DUE base provides basic 3D print control, allowing users to insert selected motor drives, extruder controllers and any other functions required on the motherboard using the Mega compatible Shield expansion board.
As a plug-and-play expansion board, ST's EVALSP820-XS can drive RAMPS printers to run at unprecedented speeds, dramatically increasing throughput; microstep resolution is increased to 1/256 steps per microstep to ensure a smooth print surface Leading the same level.
The key to achieving such a huge leap in 3D printing performance lies in ST's STSPIN820 stepper motor driver IC. The STSPIN820 embeds high-speed motor control input circuits and algorithms developed for industrial applications. It also integrates a powerful 1.5Arms output stage in a very small 4mm x 4mm QFN package with built-in comprehensive protection including undervoltage lockout, overcurrent/ Short circuit protection and thermal shutdown ensure the durability of industrial equipment.
The driver board can also be used in other development projects to accelerate the development cycle of smooth, high-speed stepper motor control, such as surveillance camera platforms, textile manufacturing equipment or sewing machines, medical equipment, money counters, office and home automation equipment, and sales terminal equipment. And robotics. The 7V-45V operating voltage range and simple host interface (including step clock and directional input pins) make the STSPIN820 versatile, economical and easy to integrate.
