Qualification status Page 4 of 19 NINA-B4 series - Application note 2 Qualification and approvals by country 2.1 European Union regulatory compliance For information about the regulatory compliance of NINA-B4 series modules against requirements and provisions in the European Union, see the NINA-B4 Declaration of Conformity [1]. 2.1.1 Radio Equipment Directive (RED) 2014/53/EU NINA-B4 series modules comply with the essential requirements and other relevant provisions of Radio Equipment Directive (RED) 2014/53/EU. 2.1.2 Output power limitation The Radio Equipment Directive requires radio transmitters that have an Equivalent Isotropically Radiated Power (EIRP) of 10 dBm or more, to either implement an adaptivity feature or reduce its medium utilization. NINA-B4 series modules are based on the Nordic Semiconductor nRF52833 chip, which supports multiple radio protocols such as Bluetooth low energy, IEEE 802.15.4 with thread, etc. Since Bluetooth low energy does not support either adaptivity or reduced medium utilization, a NINA-B4 Bluetooth LE implementation on the European market must have an EIRP of less than 10 dBm. In the European market, it is the end-product manufacturer that must ensure that these limitations are followed. If the u-blox module integrator is not the end-product manufacturer, the module integrator must make sure that this information is shared with the end product manufacturer. Radio protocols based on 802.15.4, which supports adaptivity is allowed an EIRP of 10 dBm or higher. EIRP is calculated as:

EIRP(dBm) = PTX(dBm) L(dB) + GTX(dBi) where, PTX is the output power of the transmitter, L is the path loss of the transmission line between the transmitter and antenna, and GTX is the maximum gain of the transmit antenna. Consider the following for each of these components:

Output power:

o Output power setting of the NINA-B4 module - An end product user must not be able to increase the setting above the 10 dBm EIRP limit by sending configuration commands, etc. o The operating temperature of the end product The output power of a transmitter is typically increased as the ambient temperature is lowered. The operating temperature range of NINA-B4 is -40 to +105 C, and across this range the output power can typically vary by 1 dB. The output power at the lowest operating temperature (yielding the highest output power) must be considered for the EIRP calculation. Path loss Long antenna cables or PCB traces, RF switches, etc, attenuate the power reaching the antenna. This path loss should be measured and taken into consideration for the EIRP calculation. Antenna gain - The maximum gain of the transmit antenna must be considered for the EIRP calculation. UBX-20037320 - R04 C1-Public+

Qualification and approvals by country Page 5 of 19 NINA-B4 series - Application note 2.1.3 Compliance with the RoHS directive NINA-B4 series modules comply with the Directive 2011/65/EU (EU RoHS 2) and its amendment Directive (EU) 2015/863 (EU RoHS 3). 2.2 United States (FCC) NINA-B4 series modules have received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C Intentional Radiators in accordance with Part 15.247 and Modular Transmitter approval in accordance with Part 15.212. Provided no changes or modifications are made to the module circuitry, the modular approval of the NINA-B4 series allows an end-product manufacturer to integrate the module into an existing product without the need for additional testing or equipment authorization for the transmitter function in NINA-B4 modules. Changes or modifications could void the users authority to operate the equipment. The end-user must comply with all instructions provided by the Grantee, which describe the installation and/or operating conditions necessary for compliance. The finished product is required to comply with all applicable FCC equipment authorizations regulations, requirements, and equipment functions that are not associated with the transmitter module. For example, compliance against regulations for other transmitter components within the host product must be demonstrated, and the requirements for unintentional radiators (Part 15 Subpart B Unintentional Radiators), such as digital devices, computer peripherals, radio receivers, etc., must also be met. Any additional authorization requirements (for verification or conformity declarations) that are not related to transmitter functions in the module transmitter may also contain any required digital logic functions. 2.2.1 FCC compliance NINA-B4 series modules are intended for OEM integrators only. The end product must be professionally installed in way that only authorized antennas can be used. The (OEM) Integrator must assure compliance of the entire end product that includes the integrated NINA-B4 module. For compliance with FCC Part 15B (15.107, and if applicable the 15.109 regulations, the host manufacturer is required to show conformant operation of the installed product. The product evaluation should also confirm that the intentional emissions (15C) from the module are compliant during (fundamental and out-of-band) transmission. Additionally, the integrator must apply the appropriate equipment authorization (verification) for the new host device as defined in 15.101. The details of the module implementation in host device are confidential. Integrators are reminded not to share the installation instructions of the module to any end-user of the final host device. The final host device, into which this RF module is integrated must be labeled with an auxiliary label stating the FCC ID of the RF Module, such as:

Contains FCC ID: XPYNINAB4

"This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference, and 2. This device must accept any received interference, including interference, that might cause undesired operation.

"Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the users authority to operate the equipment."

Qualification and approvals by country Page 6 of 19 NINA-B4 series - Application note The Integrator is responsible for satisfying SAR/ RF exposure requirements once the module has been integrated into the host device. NINA-B4 series modules are intended for OEM integrators only. End-products that include u-blox modules must be professionally installed in such a way that only the authorized antennas listed included in the Pre-approved antennas list can be used. If the antenna connector is easily accessible to the end-user, only Reversed Polarity SMA connectors are allowed in the final end user product. The details of the module implementation in the host device (end-product) should remain confidential. Integrators are reminded not to share the module installation instructions to the end-user of the end-product (host device). Any changes or modifications NOT explicitly APPROVED by u-blox AG may invalidate compliance with FCC rules part 15 and subsequently void the user's authority to operate the equipment. Any changes to hardware, hosts, or co-location configuration may require new radiated emission and SAR evaluation and/or testing. The end-product manufacturer (OEM integrator) is responsible for verifying the end-product compliance with FCC Part 15, subpart B limits for unintentional radiators through an accredited test facility.

The size of the label is 7.5 x 7.5 mm and contains the following information:

A Data Matrix formatted bar code, with a unique serial number Date of unit production formatted YY/WW (year/week) Major and minor product version info Product marketing name (e.g. NINA-B401, NINA-B411) u-blox logo, the red dot of the logo also indicates the location of module pin-1. Figure 1: Label location of the NINA-B4 modules Figure 2: Actual size of the NINA-B401and NINA-B411 identifier marking (7.5 x 7.5 mm) The modules are SMT components shipped to the OEM-integrator on Tape&Reel packed in a sealed Dry-Pac bag and mounted onto the host board by automatic Pick&Place machines. As the module is a surface mount device that is soldered onto the host it is not possible to place the label on the secondary side of the module. To be able to fit the FCC/IC certification number on the label the font size has to be smaller than 4 points. Using such small font size makes the certification number too small to be readable. Therefore in accordance with CFR 47 2.925 (f) the FCC IDs is not printed on the label but instead placed in the user manual and placed on the device packaging (e.g. Dry-Pac bag). The user manual also contains instruction on how to attach an auxiliary label on the end-product in compliance with the modular approval guidelines. The instructions will call attention to place the auxiliary label on an exterior surface of the device such that it will be visible upon inspection. The auxiliary label will have at least the information shown in Figure 3. This device contains FCC ID: XPYNINAB4 IC: 8595A-NINAB4 Figure 3: Auxiliary label of NINA-B401and NINA-B411 NINA-B4 series batch label for Dry-Pac and Box:

Module variant Chipset Antenna configuration Module size NINA-B400 nRF52833 u.fl NINA-B401 nRF52833 Antenna pin 10.0 * 15.0 mm 10.0 * 11.6 mm NINA-B406 nRF52833 Integrated PCB trace antenna 10.0 * 15.0 mm NINA-B410 nRF52833 u.fl NINA-B411 nRF52833 Antenna pin 10.0 * 15.0 mm 10.0 * 11.6 mm NINA-B416 nRF52833 Integrated PCB trace antenna 10.0 * 15.0 mm The printed wiring board have identical layer stack-up and dielectric properties Impedance controlled traces and other RF-related parts of the layout, except for the antenna configurations (NINA-B401 and NINA-B411 has its RF-port presented at a solder land to be connected to an external antenna connector using the external antenna reference design), are identical The difference between NINA-B401 and NINA-B411 compared to NINA-B400 and NINA-B410 besides the antenna configuration, is that two filtering capacitors are changed from 0P9 to 1P0 and 1P2 to 1P3 to keep the similar peak output and spurious emissions performance as in the original filing. Besides the differences described above, the listed module versions are identical in terms of the mounted HW components and Firmware that defines all RF characteristics. To verify that the new module version complies with the limits of the original grant, additional measurements for Peak output power and conducted spurious emissions has been performed using NINA-B401.
