The DUT can be turned on and off with a power switch controlled from the PPK desktop application.
EEPROM
On the PPK, there is an EEPROM memory connected to the nRF52832 SoC. EEPROM is used to store calibration
data.
Display interface and joystick
Reserved for future use.
3.2 The Power Profiler Kit connectors
Access to the PPK is available from a set of connectors.
The PPK has five connectors on the top side:
• Two connectors for the power supply: one for external DUT to provide precise control of the voltage and
one for the USB
• One for connecting the custom/external hardware
• One for connecting an external trigger
• One connector for connecting an external SEGGER J-Link
The connectors on the bottom side are for connecting the PPK to an nRF5x DK, which supplies both data
interface and power to the PPK.

Connector
Description
External 5 V power supply input (
J1
)
(USB)
This USB connector on the PPK supplies the on-board analog
measurement circuitry and the on-board regulator with 5 V provided
by a USB host.
This connector is used when the PPK is used standalone or any time
the USB on the nRF5x DK is not connected.
Important:
When used with an nRF5x DK with USB
connection, this connector must not be used.
External DUT output (
P16
)
The External DUT connector provides power to the DUT.
