User Manual

Introduction

The MDL NRF24L01+ 02 Transceiver Module (the module) is a System in Package (SiP) module used to transmit and receive in the 2.4GHz band.
The module has Nordic Semiconductor nRF24L01+ Single Chip 2.4GHz Transceiver on-board to perform RF send and receive functions on the front end with an SPI interface and input/output buffers to communicate with a microprocessor.

List of Applicable FCC Rules

This module must comply with all guidelines specified for Single Modular Transmitters as defined by FCC 47 CFR § 15.212(a) (1):
(a) Single modular transmitters consist of a completely self-contained radiofrequency transmitter device that is typically incorporated into another product, host or device. Split modular transmitters consist of two components: a radio front end with antenna (or radio devices) and a transmitter control element (or specific hardware on which the software that controls the radio operation resides). All single or split modular transmitters are approved with an antenna. All of the following requirements apply, except as provided in paragraph (b) of this section.
(1) Single modular transmitters must meet the following requirements to obtain a modular transmitter approval.
(i) The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements.
(ii) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over-modulation.
(iii) The modular transmitter must have its own power supply regulation.
(iv) The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). The “professional installation” provision of § 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section.
(v) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with part 15 requirements. Unless the transmitter module will be battery-powered, it must comply with the AC line conducted requirements found in § 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites unless they will be marketed with the module (see § 15.27
(a)). The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available (see § 15.31(i)).
(vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number.
(A) If using a permanently affixed label, the modular transmitter must be labeled with its own FCC identification number, and, if the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: YZHMDLNRF24L0102” or “Contains FCC ID: YZHMDLNRF24L0102”. Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explains this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization.
(B) If the modular transmitter uses an electronic display of the FCC identification number, the information must be readily accessible and visible on the modular transmitter or on the device in which it is installed. If the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains FCC certified transmitter module(s).” Any similar wording that expresses the same meaning may be used. The user manual must include
instructions on how to access the electronic display. A copy of these instructions must be included in the application for equipment authorization.
(vii) The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization.
(viii) The modular transmitter must comply with any applicable RF exposure requirements in its final configuration.

Allowable Antennas to Use with the SiP Module

MDL NRF24L01+ 02 has a straight solid core, 24AWG, 30 +/-1 mm long wire antenna soldered to the wire pad labeled ANT1. The antenna serves as a quarter-wave monopole in the 2.4GHz band. There are no additional connectors on the PCB for use with other antennas

FCC Compliance Information
Integrator is reminded to assure that these installation instructions will not be made available to the 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: YZH MDLNRF24L0102
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction, may cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
– Reorient or relocate the receiving antenna
– Increase the separation between the equipment and receiver
– Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
– Consult the dealer or an experienced radio/TV technician for help
Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
