dsPIC33FJ12MC202 Pin Allocation
Since the dsPIC33FJ12MC202 device is an I/O
remappable device, the functionality for each pin can
be defined by the user. Table 1 lists the different pins
and the functionality assigned to the pin.

Hardware Setup
ACCESSING THE HIGH VOLTAGE POWER
MODULE
Before removing the lid, the following procedure should
be rigidly followed:
1. Turn off all power to the system.
2. Wait a minimum of 3 minutes so that the internal
discharge circuit has reduced the DC bus volt-
age to a safe level. The red LED bus voltage
indicator visible through the top ventilation holes
should not be lit.
3. Verify with a voltmeter that discharge has taken
place by checking the potential between the plus
(+) and minus (–) DC terminals of the 7-pin
output connector before proceeding. The
voltage should be less than 10V before
proceeding to the next step.
4. Remove all cables from the system.
5. Remove the screws fixing the lid to the chassis
and heat sink on the top and bottom.
6. Slide the lid forward while holding the unit by the
heat sink.
7. After the board is out of the housing, modify the
power module as described in the next section.

WARNING: If the voltage is more than 10V,
repeat steps 2 and 3 until the voltage level is less
than 10V. The system is only safe to work on if the
voltage is less than 10V. Failure to heed this
warning could result in bodily harm.
