NINA-B40 series - Data sheet 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.

NINA-B40 series - Data sheet 2 Interfaces 2.1 Power management 2.1.1 Module supply input (VCC) NINA-B40 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-B40 series - Data sheet 2.2.3 Direction Finding (AoA/AoD) NINA-B40 modules support a location Bluetooth 5.1 service called Bluetooth Direction Finding. This service is used for indoor positioning, wayfinding, and tracking assets. These phase-based functions require an antenna array, estimation algorithms and processing power to make it possible to triangulate and detect the direction of a Bluetooth signal down to a sub-meter accuracy.
NINA-B40 series - Data sheet 2.3.1.2.1 Constant latency You can configure the CPU and other programmable peripherals to use minimal resources. The module can be turned on from sleep (System OFF mode) with constant and predictable CPU wakeup latency, but not without introducing some degradation in the power efficiency. 2.3.1.2.2 Low-Power The module draws least power in the (default) Low-power mode of NINA-B40 modules.
NINA-B40 series - Data sheet 2.4 Low Frequency Clock (LFXO) NINA-B40 modules require two clocks, a high frequency clock and a low frequency clock. The high frequency clock is provided on-module by a high-accuracy 32 MHz crystal as required by the radio operation. The low frequency clock can be provided internally by an RC oscillator or synthesized from the fast clock, or externally by a 32.768 kHz crystal. An external crystal provides the lowest power consumption and greatest accuracy.
NINA-B40 series - Data sheet o 1 stop bit Default frame configuration is 8N1, meaning eight (8) data bits, no (N) parity bit, and one (1) stop bit. Frames are transmitted in such a way that the least significant bit (LSB) is transmitted first. 2.5.2 Serial peripheral interface (SPI) NINA-B40 supports up to four Serial Peripheral Interfaces with serial clock frequencies of up to 32 MHz.
NINA-B40 series - Data sheet The master side of an I2S interface always provides the LRCK and SCK clock signals, but some master devices cannot generate a MCK clock signal. NINA-B40 can supply a MCK clock signal in both master and slave modes to provide to those external systems that cannot generate their own clock signal. The two data signals - SDIN and SDOUT allow for simultaneous bi-directional audio streaming. The interface supports 8, 16, and 24-bit sample widths with up to 48 kHz sample rate. 2.5.
NINA-B40 series - Data sheet 2.7.1 Analog to Digital Converter (ADC) The Analog to Digital Converter (ADC) is used to sample analog voltage on the analog function enabled pins of the NINA-B40. Any of the 8 analog inputs can be used. Characteristics of the ADC include: Full swing input range of 0 V to VCC.
NINA-B40 series - Data sheet Since the run current of the low power comparator is very low, it can be used as an analog trigger to wake up the CPU when the module sleeps in the System OFF mode. See section 2.3.1 for additional information. 2.7.4 Analog pin options Table 4 shows the supported connections of the analog functions. ☞ An analog pin may not be simultaneously connected to multiple functions.
NINA-B40 series - Data sheet 2.8.1 Drive strength All GPIO pins are normally configured for lfow current consumption. Using this standard low-drive strength, any pin configured as an output can only source or sink a certain amount of current. If the timing requirements of any digital interface cannot be met, or if an LED requires more current than is available in this mode, a high drive strength mode is available so the digital output can draw more current. See section 4.2.8.
