Geckodrive Stepper Motor Controller, 7 A, 80 V dc

The G203V is the new generation CPLD-based microstep drive. It has short-circuit protection for the motor outputs, over-voltage and under-voltage protection, over-temperature protection, reversed power supply polarity protection and will survive accidental motor disconnects while powered-up. The “V” in G203V stands for “Vampire” as it is an unkillable drive.
The G203V uses a synchronous PWM design that is absolutely silent when the motor is stopped or turning slowly. It virtually eliminates stopped-motor heating regardless of power supply voltage. The G203V is a jumper-free drive. There are no internal user settings at all so there is no need to ever remove the drive cover at all.

STEP, DIRECTION and DISABLE inputs are opto-isolated
These inputs are +2.5/3.3/5 VDC compatible
Direction is clocked in on the active step pulse edge
Needs heatsinking for current settings greater than 3 amps
LED-status indicators
Power supply voltage between 15 and 80 VDC
