NINA-B41 - data sheet 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.

NINA-B41 - data sheet Figure 1: NINA-B41 software structure 1.5.1 u-connectXpress software NINA-B41x-0xB modules are pre-flashed with u-connectXpress software, and are delivered with u‑blox secure boot loader. The u-connectXpress software enables use of the Bluetooth low energy functions, controlled by AT commands over the UART interface. Examples of supported features are u-blox low energy Serial Port Service, GATT server and client, central and peripheral roles, and multi-drop connections.
NINA-B41 - data sheet 2 Interfaces 2.1 Power management 2.1.1 Module supply input (VCC) NINA-B41 series modules use integrated step-down converters to transform the supply voltage presented at the VCC pin into a stable system voltage. Consequently, the modules are compatible for use in battery powered designs – without the need of an additional voltage converter.
NINA-B41 - data sheet The NFC interface can be used to wake the module from sleep mode, which means that the module can be kept in the deepest power save mode and still wake up properly to react to an NFC field. Two pins are available for connecting to an external NFC antenna: NFC1 and NFC2. 2.3 System functions The NINA-B41 series modules are power efficient devices capable of operating in different power saving modes and configurations.
NINA-B41 - data sheet During standby mode, the module is clocked at 32.768 kHz, which is generated by an internal RCoscillator. 2.3.3.2 Sleep mode Sleep mode is the deepest power saving mode of NINA-B41 modules. During sleep mode, all functionality is stopped to ensure minimum power consumption. The module needs an external event in order to wake up from the sleep mode. The module always reboots after waking up from the sleep mode.
NINA-B41 - data sheet 2.5.1 GPIO NINA-B41 series modules have a versatile pin-out. In an un-configured state, the modules support a total of 26 GPIO pins with no analog interfaces. All interfaces or functions must be allocated to a GPIO pin before use. 2.5.2 Universal Asynchronous Receiver/Transmitter (UART) There are two UART interfaces that may be used on NINA-B41; a primary and a secondary interface.
NINA-B41 - data sheet 2.5.2.2 Secondary UART interface The secondary UART interface can be used to "daisy chain" UART connections. It is useful in resource constrained systems where the host controller only has one UART interface available. To use it, the NINA-B3 module is configured to become a UART bridge, and UART data sent over the primary UART interface flows into the secondary UART interface. The secondary UART interface pins can be freely configured to any free NINA GPIO pins.
NINA-B41 - data sheet 3 Pin definition 3.1 NINA-B41 series pin assignment The pin-out as shown in Figure 2 describes the pin configuration used by the u-connectXpress software. Figure 2: NINA-B41 series pin assignment (top view) The grey pins in the center of the modules are GND pins. The outline below the dotted line as shown in Figure 2, the antenna area of the NINA- B410 and NINA-B416 begins. The four grey pins with dotted outlines in the antenna area are GND pins and are only present on NINA-B416.
