Description
1PCS Stepping Motor Driver Stepstick ST820 Smallest 45V Microstepping Peak Current 2.5A RMS Current 1.5A For RAMPS VS TMC2100
Product Introduction:
  ST820 is a compact and easy to use evaluation board for the STSPIN820, the world’s smallest 45 V microstepping motor driver rated at 2.5 A.It provides a very compact solution to evaluate the performance of the STSPIN820 stepper motor driver with a minimum set of additional equipment and without the need of additional devices. The hardware is fully compatible to be used together with RAMPS or other similar FFF 3D printing platforms, representing a very fast drop-in replacement of similar solutions. Contrary to most other competitors solutions, it helps customers to really exploit the benefits of working at high microstepping resolution. The microstepping resolution can be easily set to one of eight available values through M1, M2 and M3 inputs: full-step, 1/2, 1/4, 1/8, 1/16, 1/32, 1/128 and 1/256 of step. It is simply controlled through step and direction ports and embeds the PWM current control algorithm with selectable decay mode (fast + slow or slow) and the adjustable reference voltage level through an embedded potentiometer. The STSPIN820 features a full set of protections making it a bullet proof device for a wide range of industrial applications.
