Document history Version Date Author Comments V0.1 19/11/2018 Gilles Ronco Initial Table 1 : Document versions References [1] Semtech – Datasheet SX1272 Purpose This document is dedicated to NEMEUS MM002-xx-US radio module.
Module features The MM002-xx-US is a long range / low power wireless module operating in US/ CANADA ISM band (915Mhz). With interferers’ robustness and low power consumption, it is the best solution for applications requiring long range, maximum battery lifetime and secure radio link. This module integrates a SX1272 LoRaTM transceiver from Semtech and a low power ARM Cortex M3 controller.
General description The MM002-xx-US module is a long range, high-performance, solution for wireless bi-directional communication using patented LoRa™ technology from Semtech company. It operates in the US/CANADA 915 MHz frequency band and includes all necessary components for an easy integration in existing systems.
Module pins diagram The following figure gives the top view of the MM002-xx-EU module. Pad size on MM002: 0.8x1mm Footprint recommendations: TOP VIEW Footprint for all pads: 0.9x1.
Design recommendations With 4 layers PCB design, it is recommended to keep the 1st layer under the module without any layout and have a full ground plane on the 2nd layer (at least under the right part of the module : under RF transceiver part). Module Ground Plane Power Signals (or ground plane) Figure 2 : 4 layer PCB design All ground pads must be connected to ground. In case of ground planes on different layers, these one must be connected together through via.

Module pinning description Module pins functions can be configured by specific software. Description of possible configurations is provided at the end of this specification for reference. Whatever the pins configuration made by embedded software, some of them have unique functionality.
Default pinning configuration (modem controlled by AT command) With AT command modem software, only few pins are configured and used. Other ones have no specific functions and are not driven by embedded software. These extra pins must be kept Unconnected. Default modem software manages UART2 to communicate with application processor or similar. In this configuration following pins are configured.

FCC REGULATORY APPROVAL The MM002-LS-US module has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C “Intentional Radiators” modular approval in accordance with Part 15.212 Modular Transmitter approval. Modular approval allows the end user to integrate the MM002-L-US module into a finished product without obtaining subsequent and separate FCC approvals for intentional radiation, provided no changes or modifications are made to the module circuitry.
The user's manual for the finished product should include the following statements: Any changes or modifications to this equipment not expressly approved by [Name_of_OEM/Integrator] may cause harmful interference and void the user’s authority to operate this equipment. RF EXPOSURE The FCC grant is valid only when the module is sold to OEM integrators and must be installed by the OEM or OEM integrators.
CANADA (ISED) REGULATORY APPROVAL The MM002-LS-US module has been certified for use in Canada under Industry Canada (IC) Radio Standards Specification (RSS) RSS-247 and RSS-Gen. Modular approval permits the installation of a module in a host device without the need to recertify the device. This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions: 1.
