1.8.3
The over-current protection circuit included on the board shuts down the drive portion
of the circuit if the board drives 1.2 amps continually for 100 ms or longer. Upon
powering up the board, the “FAULT” LED will be on. The drive circuit must be reset
manually by pressing the CLEAR FAULT button in the lower right hand portion of the
board every time the board is initially supplied with power. Otherwise, a Fault is present
when the “FAULT” LED is illuminated and must be manually reset by pressing the same
button. If you use your own motor, keep current draw less than 1.2A, as the
over-current protection circuit will not allow driving a motor at or above this rating.
1.8.4
The motors provided on the PICDEM Demo Board must be manually connected to the
Drive screw terminals. The kit includes a Microchip screwdriver to facilitate in making
these connections.
1.8.5
The JP2 jumper is normally not populated with a shunt. With no shunt present, the
board is configured for serial communications via the PICmicro
Connecting a shunt between the bottom two pins (TX and RX) allows the user to
transmit and receive serial communication via one pin (jumper between the
microcontroller and the TX/RX pin on JP2).

The supplied Brushed DC motor and Bipolar Stepper motor are subject to
change as the motor manufacturers cannot guarantee the same model
numbers will be available indefinitely. Please refer to Microchip’s web page
(www.microchip.com) for the current data sheets for the motors supplied
with this kit, if the motor supplied on your board differs from the motor data
sheets found on the CD-ROM.
