Power Profiler Kit v1.1.0

Connectors

Access to the Power Profiler Kit (PPK) is available from a set of connectors.

The PPK has five connectors on the top side:

The connectors on the bottom side are for connecting the PPK to an nRF5 DK , which supplies both data interface and power to the PPK.

Connector Description
External 5 V power supply input (USB; J1)

This USB connector on the PPK supplies the onboard analog measurement circuitry and the onboard 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 nRF5 DK is not connected.

Note: When used with an nRF5 DK with USB connection, this connector must not be used.
External DUT output (P16) The External DUT connector provides power to the DUT.
External DUT supply input (P22) A lab power supply from 1.8 to 3.6 V can be connected here to provide precise control of the voltage.
External trigger (P20) This connector allows you to:
  • Feed an external trigger to the PPK (15 V max)
  • Have the PPK send a trigger signal to external instruments

The voltage of the TRIG OUT pin can be configured by the TRIG REF on the PPK board which has the following options:

  • VDD: default
  • 5 V: cut SB7 and solder SB8
  • External voltage: cut SB7 and SB8 (if shorted) and connect to TP5 (EXT)
External SEGGER J-Link (P21)

Used to connect an external SEGGER J-Link for communicating with the desktop application when:

  • The PPK is used standalone
  • The SEGGER J-Link on the nRF5 DK is used for debugging of the nRF5 chip on the Development Kit (DK)

If this connector is in use and the PPK is connected to an nRF5 DK, the COM switch (SW3) must be in the EXT position to disconnect the PPK from the SEGGER J-Link on the DK. How to connect and use is described in PPK switches.
