Product Name: ST820 Stepper Motor Driver
Product ID: —
Description: The ST820 is a compact evaluation board for the STSPIN820, recognized as the smallest 45V microstepping motor driver in the world.
Features:
• The power supply voltage ranges from 7V to 45V.
• Each motor phase has an output current reaching up to 1.5A rms.
• The maximum current can surge up to 2.5 A per phase due to integrated low RDS(ON) power stages (HS LS = 1 Ω typ.)
• The product enables users to utilize high microstepping resolution benefits.
• Users can conveniently set the microstepping resolution to one of the eight available options (full-step, 1/2, 1/4, 1/8, 1/16, 1/32, 1/128 and 1/256 of step) via M1, M2, and M3 inputs.
• The current is adjustable through a potentiometer, enabling the user to set the reference voltages.
• The product has embedded PWM current control with a selectable decay mode (fast or slow).
• The hardware is compatible with RAMPS or similar FFF 3D printing platforms, making it an easy replacement for similar solutions.
• The STSPIN820 allows for a compact evaluation of the performance of the STSPIN820 stepper motor driver without requiring additional equipment or devices.
• It includes full protection features such as stepper motor driving with a microstepping resolution up to 1/256th of step, overcurrent, short-circuit, and overtemperature protection.
Package includes: 10 x Microstepping ST820 Stepper Motor Driver units.
