The RAMPS Modular Platform is reducing the barriers to 3D Print Fuse Manufacturing (FFF) technology, allowing equipment manufacturers, small businesses and home users to quickly develop prototypes, manufacture components, or assist teaching. The Arduino Mega 2560 or Arduino DUE baseboard provides basics With the 3D printing control function, the user can use the Mega compatible Shield expansion board to insert the selected motor driver, extruder controller and any other functions required on the motherboard.
As a plug-and-play expansion board, ST's EVALSP820-XS can drive RAMPS printers to run at an unprecedented speed, dramatically increasing throughput; microstep resolution from 1⁄2 step to 1/256 step per microstep, ensuring the print surface Smoothness leads the same level.
Key to achieving such a quantum leap in 3D printing performance is the ST SPIN820 stepper motor driver IC from STMicroelectronics. The STSPIN820 embeds high-speed motor control input circuits and algorithms developed for industrial applications and is also integrated in the extremely small 4mm x 4mm QFN package. Powerful 1.5Arms output stage, built-in comprehensive protection features, including undervoltage lockout, overcurrent/short circuit protection and thermal shutdown, to ensure the durability of industrial equipment.
The driver board can also be used for other development projects to speed up the development cycle of smooth, high-speed stepper motor control, for example, surveillance camera platforms, textile manufacturing equipment or sewing machines, medical equipment, money counting machines, office and home automation equipment, sales terminal equipment And Robotics. The 7V-45V operating voltage range and simple host interface (including step clock and direction input pins) make the STSPIN820 versatile, economical, and easy to integrate.
EVALSP820-XS expansion board is now available.
