Hardware

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. 

■

Disconnect the RS-232 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.

Programming Interface

This kit allows programming in two modes:

■

Using the on-board programming interface 

■

Using the JTAG/SWD programming interface with a MiniProg3

The on-board programmer interfaces with your PC through a USB connector, as shown in
