Functional Description

The Cerebot MC7 is designed for use in embedded motor control applications as well as general microprocessor
experimentation. Firmware suitable for many applications can be downloaded to the Cerebot MC7's
programmable dsPIC33 microcontroller using the on-board programmer/debugger circuit.
Refer to the Cerebot MC7 schematic diagram available from the Digilent web site (www.digilentinc.com) for
detailed information about the arrangement of the various circuit features on the board.
The board provides four independent half bridge circuits capable of up to 5A continuous current. These half
bridges are connected to the Motor Control PWM Module in the dsPIC microcontroller and can be used
individually or in various combinations to drive various external loads, such as brushed DC motors, brushless DC
motors, stepper motors, and so on.
A switching 5V, 4A regulator with input voltage up to 24V is provided on the board to simplify operation of the
board from a single power supply in embedded application, such as robots.
The board has a variety of input/output connection options, and is specially designed to work with the Digilent line
of Pmod peripheral modules with various input and output functions. For more information, see
www.digilentinc.com. In addition to the Pmod connectors, the board provides two push buttons and four LEDs for
user i/o, as well as providing connections for two I2C busses. A serial EEPROM is provided on one of the I2C
busses.
