Description

Tiny Board has been designed around LV8772 IC from On-Semi. This driver is capable of micro-step drive and supports 4W 1-2 phase excitation. It has Low on Resistance with motor current selectable in four steps. The board is equipped with unusual condition warning LED and input Pulse Monitor LED. It is most suitable for the drive of a stepping motor for OA, amusements, hobby CNC, 3D printers, automatic machines, linear guides, motion control systems, XY gantry, Camera focus and zoom controller, Mini camera Pan Tilt Head.

Specifications Power Supply input 9V to 30V (Max 32V) Output Current 2.5Amps Very low noise and smooth operations Very low noise in slow speed Low on resistance (Total of upper and lower: 0.55ohms) Micro-Step mode can be set to Full-Step, 1/2 Step,1/4,1/16 Steps Motor Current selectable in four steps Output short circuit protection circuit incorporated (IC) Built in thermal shutdown circuit No Control power supply required Input Signals 1. Step (Clock) 2. Direction 3. Enable 4. Reset This Drive default set to enable and reset Current Setting via onboard Preset (Potentiometer) Attenuation ATT1 and ATT2 by Jumpers Two Jumpers for Micro-Step settings On-Board Fault Warning LED On-Board Pulse Input indication LED From:http://www.electronics-lab.com/project/2-5a-bipolar-stepper-motor-driver-lv8772e/
