The regulated outputs, VOUT1 and VOUT2, and the unregulated outputs, VBUSOUT and VSYS, are accessible on the nPM1304 EK through pin headers and probe loops.
The connection options are the following:
- Pin headers—use to power other devices like the nRF54L15 Development Kit (DK), nRF5340 Audio DK, or custom hardware.
- Probe loops—use to test the performance of the nPM1304 Power Management Integrated Circuit (PMIC) using lab equipment like electronic load, a Source Measure Unit (SMU), oscilloscope, or the Power Profiler Kit II (PPK2).
In addition, load switches or Low-Dropout Regulator (LDO) outputs are available on pin headers. For more information, see Load switches and LDOs.
The following figure shows the pin headers and probe loops for the power outputs on the nPM1304 EK.
