Overview
The Digilent PmodHB5 TM 2A H-Bridge Module
(the HB5) is an ideal solution for robotics and
other applications where logic signals are used
to drive small to medium-sized DC motors,
such as the Digilent motor-gearbox.
Features include:
• a 2A H-bridge circuit for voltages up to
12V
• a JST 6-pin connector for direct
connection of Digilent motor-gearboxes
• a 2-channel quadrature encoder with
Hall-effect sensors to detect motor
speed
• small form factor (0.8” x 1.30”)
Functional Description
The HB5 works with power supply voltages
from 2.5V to 5V, but is normally operated at
3.3V as this is the supply voltage on most
Digilent system boards.
The HB5 is designed to work with either
Digilent programmable logic system boards or
embedded control system boards. Most
Digilent system boards, such as the Nexys,
Basys, or Cerebot, have 6-pin connectors that
allow the HB5 to plug directly into the system
board or to connect via a Digilent 6-pin cable.
Some older Digilent boards may need a
Digilent Module Interface Board (MIB) and a 6-
pin cable to connect to the HB5. The MIB plugs
into the system board and the cable connects
the MIB to the HB5.
