The motor driver board makes the chip manufacturer’s in-house know-how in the field of industrial controls available for the open source 3D printer platform which enables them to upgrade the potential of the printers
STMicroelectronics EVALSP820-XS motor-driver board with the RAMPS (RepRap Arduino Mega Pololu Shield) open-source 3D-printer platform, enabling 3D printer makers to unleash the full potential of their machines for speedy printing and better surface finish.
Provides desirable functions
The Arduino Mega 2560, or Arduino DUE, baseboard provides basic control, ready for users to plug-in their own choice of motor driver, extruder controller, and any other desired functions using Mega-compatible expansion shields.
Key to the giant leap in 3D-printing performance is ST’s STSPIN820 stepper-driver IC. The STSPIN820 embeds motor-control input circuitry and algorithms developed for industrial applications
With its 7V-45V operating-voltage range and simple host interface comprising step-clock and direction-input pins, the STSPIN820 is economical and easy to integrate.
Varied applications boosting accessibility
The RAMPS (RepRap Arduino Mega Pololu Shield) modular platform has made Fused Filament Fabrication (FFF) 3D printing accessible to makers, small businesses, and home users, for fast prototyping, making replacement parts, or education.
It also integrates a powerful 1.5Arms output stage in the ultra-compact 4mm x 4mm QFN package. Industrial ruggedness is assured with built-in protection including under-voltage lockout, over-current/short-circuit protection, and thermal shutdown.
The board can be used in other projects, too, to accelerate development of smooth, high-speed stepper control for equipment such as surveillance-camera platforms, textile-manufacturing or sewing machines, medical devices, cash-handling machines, office and home automation, point-of-sale terminals, and robotics.
