EZDT17 Daughter Boards allow the user to drive a second stepper motor, bidirectional DC load or Logic level loads. The daughter board is simply plugged into the expansion connector located on the EZHR17EN.
This listing is for Logic Level loads.
EZDT17-LO TTL Level Logic Outputs Can be used to control an external Stepper Motor Driver, Or TTL, ON/OFF and PWM outputs for additional TTL Level outputs.
LOGIC LEVEL OUTPUT DAUGHTER CARD OUTPUTS STEP AND DIRECTION PULSES TO AN EXTERNAL DRIVER.
THE OUTPUTS ARE 4V, 24mA CAPABLE DRIVERS IN SERIES WITH 100 OHM RESISTORS.
THE PWM OUTPUT SETS THE CURRENT LEVEL IN THE DRIVE AND VARIES WITH THE m OR h or l (lower case L) commands.
C4 ON THE PCB CAN BE POPULATED TO SMOOTH OUT THE PWM OUTPUT AND YEILD A DC VOLTAGE
THE RESOLUTION OUTPUT CAN BE USED AS AN ENABLE LINE AND CHANGE VIA THE j2 AND j16 COMMANDS
USE COMMANDS TO SECOND AXIS EG /1aM2A1000A0R
SECOND AXIS HOMES TO SWITCH INPUTS ON MOTHERBOARD.
MAX SUPPLY VOLTAGE IS 40V WITH THIS DAUGHTER CARD.
