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 a 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 ra dio

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).

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.

Please notice that if the ISED certification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed o display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains IC: 9314A‐MDLNRF24L01” any similar wording that expresses the same meaning may be used.

This module is not a limited module 2.5 Antenna designs MDL NRF24L01+ 02 shall be manufactured with a straight, solid core, 24AWG wire 30+/‐1 mm long, and soldered into the wire pad labeled “ANT1” on the Board. PCB layout specifications are as follows: A deviation(s) from the defined parameters of the antenna of either module, as described by the instructions, require that the host product manufacturer must notify the module grantee that they wish to change the antenna design.

2.9 Information on test modes and additional testing requirements To test the module as a standalone unmodulated constant carrier, refer to Appendix C in “nRF24L01+ Product Specification.pdf” which is supplied along with this document As noted in Appendix C, the nRF24L01+ IC requires communication via the SPI lines on the IC. These are routed to the module connection pins.

2.10 Additional testing, Part 15 Subpart B disclaimer The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.249) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed if it contains digital circuity.
