Figure 3

shows how to control NINA-B50 series modules through a host CPU and interface

connections.

Figure 3: Example of NINA-B50 integration in a host system with external CPU

With NINA-B50 application designs are simplified. Developers have the option to connect an external

antenna through the antenna pin on NINA-B501 or leverage the internal antenna on NINA-B506.

Footprint compatibility with other NINA modules ensures that NINA-B50 series modules offer

maximum flexibility for developing similar devices with various radio technologies.

2.1

Power Supply

2.1.1

Power switch

series modules have an on-module power switch which can be used to switch off all or part of MCU
power supply to get lower power consumption than deep power down mode or power external devices
via

VOUT_SWITCH

The power switch input supply

VCC

is required to be supplied permanently to support standby RAM

LDO and RAM power switch. The power switch output

VOUT_SWITCH

signal can be configured to be

enabled or disabled.

The power switch can be turned on in several ways:

•

The Power-On-Reset (POR) of power switch input supply

VCC

•

External

SWITCH_WAKEUP

(pin 45). Once driven low, it can turn on power switch.

•

Internal wakeup logic from SPC if

VSYS

is powered ON.
