Power Supply Maximum Ratings
Supply voltage: 12 V
Output current (drive stage): 1.2A (total)
1.8.1
The PICDEM Mechatronics Demo Board was designed for your experimentation. After
completing the projects in Chapter 2. “Example Projects”, please experiment freely
on your own. Voltage power supplies and motors, other than those provided in the kit,
may be used.
The driver portion of the board (the part that supplies power to the motors) has an
over-current sense circuit and will trip should the motor draw more than 1.2 amps. The
LM7805 regulator also protects the circuit by limiting the current consumed by the
board. Logic has also been put in place to ensure that the P and N-Channel MOSFETs
connected to each of the output drives can not be turned on simultaneously.
1.8.2
There are eight status LEDs on the board specifically provided to assist the user in the
developing and debugging of your code. The user can output register values on one of
the Ports of the microcontroller and have a binary reading of the value of that register.
Connect the LEDs as shown in Figure 1-5. For instance, if it is suspected that the
STATUS register is not being set appropriately, move the STATUS value into PORTC.
If PORTC is attached as shown in Figure 1-5, the LEDs will show the value of STATUS.

On-Board Status LEDs
Although reasonable measures have been taken to protect the board from
the occasional mistake, THE BOARD MAY BE DAMAGED if proper design
techniques are not used and special attention to the schematic is not made.
