Using two PPK2s to measure component current consumption

nRF7002 DK Hardware

This configuration supports independent measurement of the current consumption of the nRF5340 (plus IOVDD) and the nRF7002 companion IC, using two PPK2s. See the PPK2 product page for more information.

Before you start, make sure you have prepared the Development Kit (DK) as described in Preparing the nRF7002 DK.
  1. Remove the VDD jumper on P22.
  2. Cut solder bridge SB16 and solder SB17 to disconnect the nRF5340 from VDD net and connect to the VDD_MEAS net.
  3. Connect GND on the first PPK2 kit to GND on the nRF7002 DK. You can use GND on P4 for ground.
    Note: This connection requires a berg pin connector.
  4. Connect the Vout on the first PPK2 to P22 pin 1 on the nRF7002 DK.
  5. Connect GND on the second PPK2 kit to GND on the nRF7002 DK. You can use the Li-Poly connector (P21) pin 1, labeled - (MINUS) on the Printed Circuit Board (PCB), for ground.
  6. Connect the Vout on the second PPK2 kit to P23 pin 1 on the nRF7002 DK.
Note: Ensure that you set the voltage on each PPK2 to correspond with the voltage of the connected net, as shown in the following figure.
