Page 12: Using A Voltmeter
EVK-NINA-B4 - User guide Using a voltmeter The EVK board must be modified before module current can be measured with a voltmeter. To modify the board, solder a low resistance, high tolerance, 0402 sized resistor to the footprint labeled R6. This resistor replaces the jumper normally positioned between J22 pins - 1 and 3, and any current running through it produce a voltage across its terminals. -
Page 13: Using An External Power Supply Or Power Analyzer
EVK-NINA-B4 - User guide Using an external power supply or power analyzer Connect the terminals of the instrument to the EVK pins, as shown in Figure 5. An ampere meter can also be added in series. Since the external voltage of any connected instrument can never perfectly match the 3.3 V generated by the EVK, some small current leakage is apparent whenever the signal from the NINA module is connected to an EVK peripheral. -

Page 18: Battery Powered, 3-1.7 V
EVK-NINA-B4 - User guide Battery powered, 3–1.7 V When using a battery, Figure 10 shows the default configuration. The battery voltage is connected to VDD_NINA, which in turn, is connected to the NINA-B4 VCC supply. If needed, a jumper can be added to J22 pins - 2 and 4 to supply LEDs and other peripherals with power, as long as this does not exceed the maximum current rating of the battery. -
Page 19: Battery Powered With Protection Diode, 2.7-1.7 V
EVK-NINA-B4 - User guide Battery powered with protection diode, 2.7–1.7 V This use case is meant to protect the battery from current back surges. When using the NFC interface, there is a risk that the applied electromagnetic field can cause back surges on the module’s power supply lines that will typically damage a non-chargeable battery. -
Page 20: External Supply, 3.6-1.7 V
EVK-NINA-B4 - User guide External supply, 3.6–1.7 V When measuring current consumption or performing other NINA-B4 module characterization measurements, it can be useful to power the module with an external source such as a lab power supply. In such cases, all jumpers can be removed and the required supply nets can be fed externally by connecting to the pin headers. -
