Thank you for your purchase of MOTOR-2 dual stepper motor controller board. MOTOR-2 board is a powerful and flexible motor controller boards that is based on dual Allegro Microsystems A3979 Micro stepping Motor Drivers. MOTOR-2 is designed to control two unipolar or bipolar stepper with an output drive capacity of up to 35 Volts DC and 2.5 Amperes. The on-board ATMEGA168 microcontroller with a pre-programmed firmware provides additional features RS232 interface to connect to a PC COM port to control motors directly from a PC client software SPI /I2C serial interfaces to control the motors through Expansion connector 2 buttons, 2 analog inputs and 4 digital inputs to control the motors in manual mode...

MOTOR-2 supports many different modes of operation As a standalone microcontroller board As a standalone motor controller board As a motor controller peripheral board for BiPOM MINI-MAX Series microcontroller boards As a motor controller peripheral board for third-party microcontroller systems As a motor controller peripheral board for a PC...
