screen, Vssa in the schematic), which connects directly to the analog ground on the board. The
other ground known simply as GND, is used for the digital and high current circuitry on the
expansion board. This differentiation on the connector grounds helps the expansion board designer
to separate the analog and digital ground on any high precision analog boards being designed for
port E.
Low Power Functionality
The kit also facilitates application development, which requires low power consumption. Low power
functions require a power measurement capability, also available in this kit.
The analog supply is connected to the device through the zero-ohm resistor (R23). By removing this
resistor and connecting an ammeter in series using the test points, Vdda_p and Vdda, you can
measure the analog power used by the system.
The digital supply can be monitored by removing connection on the jumper J10 and connecting an
ammeter in place of the short. This allows to measure the digital power used by the system.
The board provides the ability to measure analog and digital power separately. To measure power at
a single point, rather than at analog and digital separately, remove the resistor R23 to disconnect the
analog regulator from powering the Vdda and short Vdda and Vddd through R30. Now, the net
power can be measured at the J10 jumper similar to the digital power measurement. To switch
repeatedly between R23 and R30, moving around the zero-ohm resistors can be discomforting.
Hence, a J38 (unpopulated) is provided to populate a male 3-pin header and have a shorting jumper
in the place of R23/R30.
While measuring device power, make the following changes in the board to avoid leakage through
other components that are connected to the device power rails.

On-board Programming Interface
The on-board programmer interfaces with your PC through a USB connector marked as USB
programming.
Disconnect the RS232 power by disconnecting R58. An additional jumper capability is available
as J37 if you populate it with a 2-pin male header.
Disconnect the potentiometer by disconnecting J30.
Ground the boost pins if boost operation is not used by populating R1, R28, and R29. Also make
sure R25 and R31 are not populated.
