The current measurement and debug board (PCA64165) can be inserted into the current measurement and debug board connector (P9) on the Nordic Thingy:91 X™.
The current measurement and debug board simplifies the measuring of current consumption on the power domains supplying the nRF9151 System in Package (SiP) (M1), nRF7002 Wi-Fi® 6 companion Integrated Circuit (IC) (U21), and nRF5340 System on Chip (SoC) (U6) with a power profiling tool, such as the Power Profiler Kit II.
The interface also allows trace debugging and connecting external circuits or boards to the Nordic Thingy:91 X™ by using the nRF9151 SiP 's TRACE pins as regular GPIOs. The pins are configured as GPIOs by default.
The following figure describes the current measurement and debug board connector.
