2.5A Stepper Phidget

0 out of 5 based on 0 customer ratings



If you’re looking for a compact solution for controlling a medium-sized stepper motor, the 2.5A Stepper Phidget is an affordable and convenient option. You can control the position, velocity, and acceleration of the motor by sending commands from your program.

Safety Features

The STC1001 comes equipped with a heatsink to prevent the board from overheating during use. The power terminals on this device are polarity protected: if you happen to hook up the power supply backwards, the device simply won’t power up and won’t be damaged. A 5-amp automotive-style fuse is also included to protect the board from current spikes from the motor’s back-EMF. This Phidget is isolated from input to output, so your VINT hub and computer will be protected if anything goes wrong.

Power Saving Options

For power-conscious users, we also allow for separate control over the current limit and the holding current limit. If you know your motor will be stationary for long periods of time, but still needs a small amount of holding torque to maintain its position, you can set the holding current appropriately without interfering with the running current limit.
