    The internal PIFA antenna is specifically designed for the small NINA form factor and provides an extensive range. The NINA-B3 series is globally certified for use with the internal antenna or a range of external antennas. This greatly reduces time, cost, and effort for customers integrating the NINA-B3 in their designs.

    1.4.2 Digital I/O interfaces reference voltage (VCC_IO) On NINA-B3 series modules, the I/O voltage level is the same as the supply voltage and VCC_IO is internally connected to the supply input VCC. When using NINA-B3 with a battery, the I/O voltage level will vary with the battery output voltage, depending on the charge of the battery.

    DC/DC efficiency quickly degrades as idle current drops below a few mA, greatly reducing the battery life. Due to the low current consumption and wide voltage range of the NINA-B3 series module, a battery can be used as a main supply. The capacity of the battery should be selected to match the application.
