Product Description: The ST820 is a versatile evaluation board tailored for the STSPIN820, renowned as the world’s smallest 45V microstepping motor driver. With its compact design, this board presents an effortless user experience.
Key Features:
- Incorporates a supply voltage ranging between 7V to 45V.
- Delivers an output current up to 1.5A rms for each motor phase and a maximum current up to 2.5 A per phase.
- Features integrated low RDS(ON) power stages amounting to 1 Ω typically.
- Facilitates high microstepping resolution for optimal performance.
- Offers eight variable microstepping resolutions: full-step, 1/2, 1/4, 1/8, 1/16, 1/32, 1/128, and 1/256 of step. These can be easily set via M1, M2, and M3 inputs.
- Features a potentiometer for adjusting current control to set reference voltages.
- Includes embedded PWM current control with an option to select decay mode (fast or slow).
- The board’s hardware seamlessly integrates with RAMPS or similar FFF 3D printing platforms, providing a swift drop-in replacement for similar solutions.
- Offers a compact way to examine the STSPIN820 stepper motor driver’s performance without the need for additional equipment or devices.
- The STSPIN820 contains a complete set of protections, such as overcurrent, short-circuit, and overtemperature protection, and allows microstepping resolution up to 1/256th of a step.
