nRF9160 DK v0.8.5

nRF9160 supply

The nRF9160 has a supply range of 3.0–5.5 V and is therefore powered by the VSUPPLY rail directly.

In order to enable current measurements of nRF9160 directly, P24 is added to supply nRF9160 from a separate source. To enable the use of P24 during current measurements, cut solder bridge SB44. For more details on how to measure nRF9160 current, see Measuring current.

Note: No protection diodes are implemented. Make sure to connect the positive voltage to the pin next to the “+” and GND to the pin next to “−“.
