7V to 45V Microstepping ST820 Motor Driver + Heatsink for 3D Printer RAMPS

Description:
? ST820 is a compact and easy to use evaluation board for the STSPIN820, the world's smallest 45V microstepping motor driver.
Features:
? Supply voltage from 7V to 45V ? Output current up to 1.5A rms for each motor phase ? Maximum current up to 2.5 A per phase Integrated low RDS(ON) stages (HS + LS = 1 Ω typ.) ? 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 inputs: full-step, 1/2, 1/4, 1/8, 1/16, 1/32, 1/128 and 1/256 of step. ? Can adjustable current control through a potentiometer to set the ref. voltages Embedded PWM current control with selectable decay mode (fast or slow) ? The hardware is fully compatible to be used together with RAMPS or similar FFF 3D printing platforms, representing a very fast drop-in replacement of similar solutions. ? It provides a very compact solution to evaluate the performance of the STSPIN820 motor driver with a minimum set of additional and without the need for additional devices. ? The STSPIN820 features a full set of protections: – motor driving with a microstepping resolution up to 1/256th of step – Overcurrent, short-circuit and overtemperature protection
