BC4D15 Four Motor Controller

The BC4D15 controller board is a complete Bipolar four-axis stepper motor controller system implemented on a small 3.45 inch wide by 2.25 inch tall board (as shown here).  It includes the capability of driving up to four bipolar stepper motors at high speeds using current control techniques.  This unit is a good choice for those designing products which require higher motor speeds, since it can easily "over-voltage" the motor (to attain the higher speed) without overloading it.

Please look here for the updated version of this board, the BC4E15.  This version adds a built-in USB interface, as well as ESD protection.

The BC4D15 board directly supports TTL-Serial communication, as used between microprocessor chips.  The RS232ToTTL and USBToTTL communications boards may be ordered if you wish to use RS232 or USB communications as your method of communication.

This product requires that you select a power supply whose voltage and current can handle your stepper motor.     You will first want to review the calculating motor current for current controlled products faq in order to determine the current and voltage requirements for your motor.

The board can operate bipolar motors from about 0.2 to 1.3 amps/winding when used as a continuous duty device, and it can handle up to 1.5 amps per winding when used in intermittent service (no more than 30 seconds of the motor being on, followed by at least 30 seconds being off).

This board is normally configured with the BC4D15PotRouter  firmware. This firmware combines all of the key capabilities of the BC2D15PotStepper and BC2D15PotRouter firmwares (as implemented on the 2 motor controller, the BC2D15), and adds a few more capabilities as well.

The board can also be configured with our BC4DNCRouter firmware for the BC4D15 product line.  This firmware allows control of 4 stepper motors in a 'linked' fashion, as is appropriate for Numerically Controlled operations.  Please click here for more information....
