8.4 Power Measurements
The 96Boards CE specification calls for a minimum of one current sense resistor to be placed on the board permitting a basic
power measurement functions.
The SD 600eval supports power measurement for testing.
A 0.01ohm resistor (R18) is placed in line to the SYS_DCIN power line coming from (J2) DC Jack (please note that this power
measurement only works for SYS_DCIN from J2, it will not measure SYS_DCIN applied from the Low Speed Expansion
Connector). Placing a probe over this resistor will provide a voltage measurement across the resistor. Dividing this measurement
by 0.01ohm will give the amount of the current flowing into the board. The board provides a means to use ARM Energy probe
for this measurement at connector J15.
