Reference Design of Digilent Pmod HB5

This is a reference design of Digilent Pmod HB5 - RS Part Number: (134-6447)

The Digilent Pmod HB5 was converted into DesignSpark PCB format. Download link to the project files and the article of Digilent Pmod HB5 can be found at the end.

The Digilent Pmod HB5 (Revision E) offers a 2A H-bridge circuit to drive small to medium sized DC motors. This module was specifically designed to work with the Digilent gearbox motor which incorporates quadrature encoder feedback.

  • 2A H-bridge circuit
  • Drive a DC motor with operating voltage up to 12V
  • 6-pin JST connector for direct connection to Digilent motor/gearboxes
  • Two screw terminals for external motor power supply
