Description:
The ST820 is an easy-to-use driver board for 3D printers, routers and more. A compact solution for stepper motor drives with minimal external equipment, no additional components required.The hardware is fully compatible for RAMPS or other similar FFF 3D printing platform, representing a quick alternative to similar solutions. Unlike market solutions, the ST820 helps customers truly take advantage of high-microstepping solutions.
Microstep resolution easily settable through jumpers: full-step, 1/2, 1/4, 1/8, 1/16, 1/32, 1/128 and 1/256 of step. Simple step and direction control interface.
Adjustable current control through a potentiometer to set the ref. voltages.
Embedded PWM current control with selectable decay mode (fast or slow).
