Page 5: Introduction
Introduction The Power Profiler Kit (PPK) is an affordable, flexible tool that measures the real-time power consumption of your designs. The PPK measures power consumption for a connected nRF5 DK or any external board. It measures current from 1 μA to 70 mA and gives a detailed picture of the current profile for the user application. The PPK can be used in conjunction with the nRF5 DK to measure current on the nRF5 DK or on an external board. -
Page 6: Minimum Requirements
Minimum requirements Before you start setting up the PPK, check that you have the required hardware and software. Hardware requirements • USB cable • nRF5 DK or a standalone SEGGER J-Link debugger Software requirements • One of the following operating systems: •... -
Page 7: Kit Content
You can download the hardware files from the Power Profiler Kit product page. The hardware zip file contains the following files for the PCA63511 board: • Altium Designer files • Production files (bill of materials and assembly, drill, Gerber, and pick-and-place files) •... -
Page 8: Quick Start
Quick start Complete a few steps to set up your PPK. The PPK is connected to an nRF5 DK (not included in the package). In this quick start, the PPK measures current on the nRF5 DK, which also acts as a power supply and sends data to the Power Profiler app. -
Page 9: Hardware Description
Hardware description The PPK contains connectors and measurement components. 5.1 Measurement system The PPK is driven by the nRF52832 System on Chip (SoC), which uses its analog-to-digital converter (ADC) to measure a voltage drop over a series of measurement resistors. Resistor values are used to calculate the power consumption. -
Page 10: Measurement Ranges And Switch Levels
Hardware description When the DK is selected as the power supply, the DK supplies the PPK circuitry. The analog part of the automatic switch circuitry requires a 5 V power supply. When the PPK is connected to an nRF5 DK, the 5 V is supplied by the DK. When the PPK is used standalone, a USB cable has to be connected to supply the 5 V required by the circuitry. -

Hardware description Figure 6: Enable power output in the Power Profiler app v3.1.0 5.1.5 EEPROM On the PPK, there is an EEPROM memory connected to the nRF52832 SoC. The EEPROM is used to store calibration data. 5.2 Connectors Access to the PPK is available from a set of connectors. The PPK has five connectors on the top side: •... -

Hardware description 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 This USB connector on the PPK supplies the onboard analog (USB;... - Page 13 Hardware description Figure 8: PPK switches Switch Description DUT select (SW2) Selects if the measurements are performed on the nRF5 DK or on an external/ custom hardware. Options: • DK: The measurements are performed on the nRF5 DK. • External: The measurements are performed on the external/custom hardware connected to the External DUT (P16) connector.
- Page 14 Hardware description Switch Description COM (SW3) This switch selects the SEGGER J-Link connection. Options: • DK: The SEGGER J-Link on the nRF5 DK is used. • EXT: An external SEGGER J-Link is used and connected to the Debug in (P21) connector.

Page 15: Configuring The Ppk
Configuring the PPK Different configuration setups and methods for measuring current can be used for the PPK. To configure the PPK, complete the following steps: 1. Adjust measurement accuracy as described in Optimizing measurement accuracy on page 15. 2. Choose a use case and implement a configuration for the PPK. The options are presented in the following table. -
Page 16: Connecting The Power Profiler Kit To An Nrf5 Dk
Configuring the PPK You must include decoupling capacitors to ensure correct operation of the devices. However, as a good practice, keep extra decoupling capacitors to a minimum when measuring detailed current draw. 6.2 Connecting the Power Profiler Kit to an nRF5 DK For all of the PPK configurations, except when the PPK is running standalone, the PPK needs to be connected to the nRF5 DK. -
Page 17: Measuring Current On An Nrf5 Dk While Debugging
Configuring the PPK • The Power select switch (SW4) is in the DK position. • The COM switch (SW3) is in the DK position. • The USB cable is plugged into the USB connector on the nRF5 DK and connected to a computer with the Power Profiler app. -
Page 18: Measuring Current On Custom Hardware With An Nrf5 Dk
Configuring the PPK 6.5 Measuring current on custom hardware with an nRF5 DK This setup is to be used during the design phase on custom hardware acting as the device under test (DUT) with the nRF5 DK. In this use case, the PPK measures the current on the external DUT. The PPK is connected to the nRF5 DK which is used as a SEGGER J-Link interface to the computer running the Power Profiler app. -
