Overview
The Cerebot MC7 board is microcontroller development board based on a Microchip® dsPIC 16-bit Digital Signal
Controller.
The Cerebot MC7 is primarily intended to be used as a controller for electro-mechanical devices such as DC
motors. The microcontroller used, a dsPIC33FJ128MC706A, is a member of a dsPIC family optimized for motor
control applications.
The Cerebot MC7 provides four Half-Bridge circuits that are rated for 24V at up to 5A. Each of these Half Bridge
circuits is connected to the dsPIC A/D converter to measure voltage and current for closed loop feedback control.
These half bridges can be used to control two brushed DC motors, two bi-polar stepper motors, one brushless DC
motor, one uni-polar stepper motor. In addition, the board can be used to implement controllers for switched DC-
DC converters.
The Cerebot MC7 works with the Microchip MPLAB
®
development environment and provides built in programming
and debugging support within the MPLAB IDE.
