Development Board Hardware
4.4.6.1
DAUGHTER BOARD-SPECIFIC HARDWARE MODIFICATIONS
Depending on the PICtail Plus Daughter Board to be used, hardware modification to
the development board may be required. The modifications re-route different signals
from the microcontroller, particularly EPMP signals, to different pins of the connector.
All changes consist of placing 0 ? resistors in designated areas to enable the connec-
tions, or removing existing resistors in other places to disable existing connections. All
of the resistors are located in a single group adjacent to the Flash memory area, shown
in Figure 4-10. They are also shown as a single group in Figure A-6 of the development
board schematic.

Current Measurement
To provide additional information on developing hardware solutions, the development
board includes current measurement points at three locations. These permit the current
drawn by the different branches of the development board to be measured separately.
callouts 1,2 and 3, respectively). To measure current, cut the trace on the reverse side
of the board that shorts the two vias for the jumper, then insert the current measuring
device between the two vias.
JP3 can be used to measure the total current drawn by the board from the 9V power
supply. JP1 can be used to measure the total current (at 3.3V) drawn by the microcon-
troller, and JP2 can be used to measure the total current drawn by the remaining 3.3V
branch of the board. The current drawn by the 5V branch can be measured by subtract-
ing the sum of the currents of JP1 and JP2 from the total current measured at JP3.
