1.9 Power modes
The NINA-B2 series modules are power efficient devices capable of operating in different power saving modes
and configurations. Different sections of the module can be powered off when not needed and complex wake
up events can be generated from different external and internal inputs. For the lowest current consumption
modes, an external LPO clock is required (see section 2.2).
See the u-blox Short Range AT Commands Manual [3] and NINA-B2 series System Integration Manual [1] for
more information about power modes.
NINA-B2 series - Data Sheet
UBX-18006649 - R01 Interfaces
Page 9 of 41
2 Interfaces
2.1 Power supply
The power for NINA-B2 series modules is supplied through VCC and VCC_IO pins by DC voltage.
The system power supply circuit must be able to support peak power (add 20% as margin over the listed
type current consumption), as during operation, the current drawn from VCC and VCC_IO can vary
significantly based on the use cases.
2.1.1 Module supply input (VCC)
The NINA-B2 series modules use an integrated Linear Voltage converter to transform the supply voltage
presented at the VCC pin into a stable system voltage.
2.1.2 Digital I/O interfaces reference voltage (VCC_IO)
All modules in the NINA-B2 series provide an additional voltage supply input for setting the I/O voltage level.
The separate VCC_IO pin enables integration of the module in many applications with different voltage levels
(for example, 1.8 V or 3.3 V) without any level converters. The NINA-B2 modules support only 3.3 V as IO
voltage level currently.
2.2 Low Power Clock
The NINA-B2 series module does not have an internal low power oscillator (LPO), which is required for low
power modes. An external 32.768 KHz LPO signal can be supplied externally via the LPO_CLK pin if low power
modes are required.
The low power clock voltage level is lower (0/0.7 V) compared to the digital signal levels and a
voltage divider can be required (see section 4.2.4).
2.3 Module reset
The NINA-B2 series modules can be reset (rebooted) in one of the following ways:
Low level on the RESET_N pin, which is normally set high by an internal pull-up. This causes
“hardware” reset of the module. The RESET_N signal should be driven by an open drain, open collector
or contact switch. When RESET_N is low (off), the chip works at the minimum power.
The NINA-B2 series modules can be reset using an AT command (see the u-blox Short Range AT
Commands Manual [3]). This causes a “software” reset of the module.
2.4 Boot strapping pins
There are several boot configuration pins available on the module that needs to have the correct settings during
boot. It is important that they are in the default state (marked with bold in Table 4) during startup for normal
operation. The default state is automatically selected (with internal pull-ups or pull-downs) if the pins are left
unconnected.

2.5 RF antenna interface
The RF antenna interface of the NINA-B2 series supports Bluetooth BR/EDR and Bluetooth low energy on the
same RF antenna signal. The module is equipped with a 2.4 GHz bandpass filter between the radio chip and RF
antenna interface (see section 1.4).
The NINA-B2 series supports either an internal antenna (NINA-B222) or external antennas connected through an
antenna pin (NINA-B221).
2.5.1 Internal antenna
The NINA-B222 module has an internal (embedded) 2.4 GHz PIFA antenna. The internal antenna is a PIFA
antenna specifically designed and optimized for the NINA form factor.
Keep a minimum clearance of 5 mm between the antenna and the casing. Keep a minimum of 10 mm free
space from the metal around the antenna including the area below. If a metal enclosure is required, use
NINA-B221 and an external antenna.
It is recommended to place the NINA-B222 modules in such a way that the internal antenna is in the corner of
the host PCB (the corner closest to Pin 16 should be in the corner). The antenna side (short side closest to the
antenna), positioned along one side of the host PCB ground plane is the second best option. It is beneficial to
have a large solid ground plane on the host PCB and have a good grounding on the NINA-B222 module.
Minimum ground plane size is 24x30 mm but recommended is more than 50x50 mm.
See NINA-B2 series System Integration Manual [1] for more information about antenna related design.
The ANT signal is not available on the solder pins of the NINA-B222 module.
2.5.2 External RF antenna interface
The NINA-B221 module has an antenna signal (ANT) pin with a characteristic impedance of 50 Ω for using an
external antenna. The antenna signal supports both Tx and Rx.
The external antenna, for example, can be an SMD antenna (or PCB integrated antenna) on the host board. An
antenna connector for using an external antenna via a coaxial cable could also be implemented. A cable antenna
might be necessary if the module is mounted in a shielded enclosure such as a metal box or cabinet.
An external antenna connector (U.FL. connector) reference design (see NINA-B2 series System Integration
Manual [1]) is available and must be followed to comply with the NINA-B2 FCC/IC modular approvals.
Also see the list of approved antennas (section 7.2).

2.6.2 System control IO signals
The following input signals are used to control the system (see u-blox Short Range AT Commands Manual [3] for
more information about connectivity software signals IOs):
RESET_N is used to reset the system. See section 0 for detailed information.
If SWITCH_2 is driven low during start up, the UART serial settings are restored to their default values.
SWITCH_2 can be used to open a connection to a peripheral device.
If both SWITCH_1 and SWITCH_2 are driven low during start up, the system will enter the bootloader
mode.
If both SWITCH_1 and SWITCH_2 are driven low during start up and held low for 10 seconds, the
system will exit the bootloader mode and restore all settings to their factory defaults.
2.6.3 UART IO signals
In addition to the normal RXD, TXD, CTS, and RTS signals, the NINA-B221/NINA-B222 software adds the DSR
and DTR pins to the UART interface. Note that they are not used as originally intended, but to control the state
of the NINA module. Depending on the current configuration, the DSR pin can be used to:
Enter command mode.
Disconnect and/or toggle connectable status.
Enable/disable the rest of the UART interface.
Enter/wake up from sleep mode.
2.7 Data interfaces
2.7.1 UART
The NINA-B221 and NINA-B222 modules include a 6-wire UART for communication with an application host
processor (AT commands, Data communication, and software upgrades).
The following UART signals are available:
Data lines (RXD as input, TXD as output)
Hardware flow control lines (CTS as input, RTS as output)
Link status (DTR as output, DSR as input). The DTR/DSR signals behavior is adapted to the u-blox
connectivity software functionality and differs from the UART standard, see section 2.6.3 for additional
information.
Programmable baud-rate generator allows most industry standard rates, as well as non-standard rates
up to 921600 bps.
