1 Functional description
1.1 Overview
The NINA-B40 series comprises small, stand-alone Bluetooth 5.1 Low Energy wireless modules that
are particularly suited for harsh professional environments.
Based on the Nordic Semiconductor nRF52833 chip that includes an integrated RF core and powerful
Arm® Cortex®-M4 with FPU processor, NINA-B40 modules operate in all Bluetooth 5.1 modes – as well
as 802.15.4 (Thread and Zigbee) and Nordic proprietary modes.
Featuring Angle of Arrival (AoA) and Angel of Departure (AoD) transceivers, the NINA-B40 series
supports the Bluetooth 5.1 Direction Finding service. The service can be used for indoor positioning,
wayfinding, and the tracking of assets.
NINA-B40 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-B3 modules, NINA-B40 offers a
natural upgrade path for existing NINA-B3 applications. See also NINA-B3 Data sheet [6] and
NINA-B40 Product summary [5].
Table 1 describes the different models in the NINA-B40 series.
Model Description
NINA-B400
Bluetooth 5.1 module that includes a powerful Arm® Cortex®-M4 with FPU, and delivers state-of-the-art
power performance. All NINA-B40 variants are open CPU modules that enable customer applications to
run on the built-in Arm® Cortex®-M4 with FPU. With 512 kB flash and 128 kB RAM, these modules offer
sufficient capacity for customer applications on top of the Bluetooth Low Energy stack.
NINA-B400 has a U.FL connector for use with an external antenna.
NINA-B406
Bluetooth 5.1 module that includes a powerful Arm® Cortex®-M4 with FPU, and delivers state-of-the-art
power performance. All NINA-B40 variants are open CPU modules that enable customer applications to
run on the built-in Arm® Cortex®-M4 with FPU. With 512 kB flash and 128 kB RAM, these modules offer
sufficient capacity for customer applications on top of the Bluetooth Low Energy stack.
NINA-B406 has an internal PCB trace antenna integrated in the module PCB. The internal antennas have
an extensive range and are specifically designed for embedded devices.

☞ 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.
