• Geckodrive G540 4-Axis Digital Stepper Motor Driver
• Capable of driving four independent motors
• Integrated DB25 connector
• Runs a stepper motor up to 3.5A and 50VDC
• Motor Control Type: Stepper

The Geckodrive G540 4-Axis Digital Stepper Motor Driver is designed to run a large stepper motor efficiently and inexpensively. This is made possible due to its CPLD design, which moves most formerly analog operations to firmware while still maintaining its large dual H-bridge power section.

Its oversized MOSFETs can run a stepper motor up to 3.5A and 50VDC without issue, pushing its motor range to NEMA 17s through 34s.

The motherboard has an integrated DB25 connector for connecting directly to a computer via a parallel port or a third-party motion controller. Motor connections are made through DB9 plugs, which are included with the drive, and current can be set differently on each axis via a current set resistor.

The G250X, the heart of the G540, features proprietary anti-resonance and motor smoothing techniques. At a native ten micro-step resolution, the G250X does not require extremely high input frequencies to operate at high speed but offers enough resolution to match the accuracy of most stepper motors (+/- 5% of one full step).
