1 Functional description
The NINA-B41 series is comprised of small, standalone Bluetooth low energy wireless modules
featuring full Bluetooth 5.1. Based on the Nordic Semiconductor nRF52833 chip, NINA-B41 modules
include an integrated RF core and powerful Arm® Cortex®-M4 with FPU processor, and operate in
all Bluetooth 5.1 modes.
With an operational temperature range that spans from -40 up to +105°C, NINA-B41 modules are
ideal for harsh industrial or lighting applications that must operate at high ambient temperatures.
NINA-B41 also caters towards applications in smart buildings, smart cities, industrial automation
systems, sensor networks and asset tracking solutions.
NINA-B41 modules need only a single supply voltage in the range of 1.7 – 3.6 V and, as the supply
voltage level can also be used as the I/O reference level, can be easily integrated into simple, single
voltage rail systems. The broad supply voltage range makes the modules particularly useful in
battery powered systems.
With the same pinout, physical size and mechanical design of NINA-B31 modules, NINA-B41 offers
a natural upgrade path for existing NINA-B3 applications. See also the NINA-B3 data sheet [6] and
NINA-B41 product summary [5].
The NINA-B41 series includes the following two sub-series, as listed in the table below:
Model Description
NINA-B410 Bluetooth 5.1 module with a powerful Arm Cortex-M4 with FPU and u-connect software pre-flashed.
The u-connect software in NINA-B41 modules provides support for u-blox Bluetooth low energy Serial
Port Service, GATT client and server, beacons, NFC™, and simultaneous peripheral and central roles – all
configurable from a host using AT commands. The NINA-B410 modules provide top grade security, thanks
to secure boot, which ensures the module only boots up with original u-blox software.
NINA-B410 has an U.FL connector for use with an external antenna.
NINA-B416 Bluetooth 5.1 module with a powerful Arm Cortex-M4 with FPU and u-connect software pre-flashed.
The u-connect software in NINA-B41 modules provides support for u-blox Bluetooth low energy Serial
Port Service, GATT client and server, beacons, NFC™, and simultaneous peripheral and central roles – all
configurable from a host using AT commands. NINA-B416 modules provide top grade security, thanks to
secure boot, which ensures the module only boots up with original u-blox software.
NINA-B416 has an internal PCB antenna integrated in the module PCB. The internal antennas are
specifically designed for embedded devices and provide an extensive range.

Note Already globally certified for use with an internal antenna or range of external
antennas, the time, cost, and effort spent on deploying NINA-B4 modules into customer
applications is reduced significantly.
1.1Applications
