Design guidelines 7.1 Placement of the module The Onethinx module has an integrated LoRa antenna, which should be in free space for best results. The figure below shows the advised module positioning and corresponding pad locations. Figure 2: OTX-18 PCB design guidelines and pad placement There are library components available for several commonly-used PCB design IDEs. Please check the Onethinx website, forum and Github before creating your own. 7.
Reference design Button Light Sensor Button The design files of the Onethinx devkit are available on our website. The connection header size and positioning allow the devkit to act as a battery-powered Arduino with LoRaWAN, so you are able to add shields to it (you will need to configure the I/O of course).

Environmental Specifications 9.1 Environmental Compliance This OTX-18 module is produced in compliance with the Restriction of Hazardous Substances (RoHS) and Halogen-Free (HF) directives. The Onethinx module and components used to produce this module are RoHS and HF compliant. 9.2 RF Certification The OTX-18 module will be certified under the following RF certification standards at production release. ■ FCC: 2AUBKOTX-18 ■ CE ■ IC: ?????-???? 9.
Regulatory Information 10.1 FCC 10.1.0 List of applicable FCC Rules: The device OTX-18 complies with Part 15 of the FCC Rules (47 CFR Part 15 Subpart C §15.247). The device meets the requirements for modular transmitter approval as detailed in FCC public Notice DA00-1407. 10.1.1 Specific operational use conditions: The modular transmitter should be used within the limits outlined in Chapter 5 (Specifications) and the according the Design Guidelines (Chapter 7).
10.1.4 RF exposure considerations: To comply with FCC RF Exposure requirements, the Original Equipment Manufacturer (OEM) must ensure to install the approved antenna following the guidelines in Chapter 7. The preceding statement must be included as a CAUTION statement in manuals, for products operating with the approved antenna in Chapter 7 on page 11, to alert users on FCC RF Exposure compliance.
10.2 European Declaration of Conformity Hereby, Onethinx BV declares that the module OTX-18 complies with the essential requirements and other relevant provisions of Directive 2014.
10.3 OEM Integrator Instructions The OTX-18 module is tested with a standard SMA connector and with the antennas listed in Chapter 7 on page 11. When integrated in the OEMs product, these fixed antennas require installation preventing end-users from replacing them with non-approved antennas. Any antenna not in the following table must be tested to comply with FCC Section 15.203 for unique antenna connectors and Section 15.247 for emissions.
