Pmod DHB1: Dual H-bridge with DRV8833 motor driver chip

Description

Pmod is Digilent’s name for the line of over 60 peripheral modules that they offer to add extra functionality to both microcontrollers and FPGAs (field-programmable gate array). This functionality includes audio amplifiers, GPS receivers, USB to UART interface, seven-segment displays, accelerometers, H-bridges with input feedback, analog-to-digital converters, and much more.
There are two main categories of Pmod interface that are available: the original peripheral modules with 6 pins (or a stack of two 6-pin sets for 12 pins) and an interface that uses the I²C interface. All of the Pmod headers are designed very consistently with the standard 100 mil (0.1 inches) pitch between each of the pins.
All of the peripheral modules are powered by the host board through the power pin on the interface. The host will be able to power the Pmods at either 3.3V or at 5V power, depending on the requirements of the Pmod.

The PmodDHB1 uses the Texas Instruments® DRV8833 dual H-Bridge motor driver chip to drive two DC motors or a single stepper motor. Each H-Bridge can be driven by GPIO signals.
