Overview LoRa1276-c1-915-868 integrates Semtech RF transceiver chip SX1276, which adopts LoRa TM Spread Spectrum modulation frequency hopping technique. The features of long distance and high sensitivity (-139 dBm) make this module perform better than FSK and GFSK module. Multi-signal won't affect each other even in crowd frequency environment; it comes with strong anti-interference performance. This module is 100mW and ultra small size, widely used in AMR,remote industrial control filed. 2.

Accessories 1)Antenna antenna is very important for RF communication, its performance will affect the communication directly. Module needs antenna in 50ohm. Common antenna has rubber straight/ elbow/ foldable rod and sucker antenna and etc. Users can order accordingly. To ensure module in the best performance, we suggest to use the our antenna NiceRF Wireless Technology Co., Ltd. sales@nicerf.com Rev 1.1 - 6 - www.nicerf.com LoRa1276-c1-915 To ensure modules get the best performance, user must obey the following principles when using the antennas Put the antenna away from the ground and obstacles as possible as you could If you choose the sucker antenna, pull straight the lead wire as possible as it can be, the sucker under arches should be attached on the metal object. 9.

FAQ: a) Why module can not communicate properly? 1) Check if the band, channel, rate, NET ID has set to the same; 2) Check if there is power connection error; 3) Check if the module is enabled (CS high); 4) Check if the antenna connection is not correct; 5) Check if the module is damaged. b) Why transmission distance is not far as it should be? 1) Power supply ripple is too large; 2) The antenna types do not match, or not properly installed; 3) The surrounding environment is harsh, strong interference sources; 4) Surrounding co-channel interference; Appendix 1SMD Reflow Chart We recommend you should obey the IPC related standards in setting the reflow profile: NiceRF Wireless Technology Co., Ltd. sales@nicerf.com Rev 1.1 - 8 - www.nicerf.com LoRa1276-c1-915 NiceRF Wireless Technology Co., Ltd. sales@nicerf.com Rev 1.1 - 9 - www.nicerf.com LoRa1276-c1-915 FCC 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 interference received, including interference that may cause undesired operation. NOTE: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications or changes to this equipment. Such modifications or changes could void the user's authority to operate the equipment. RF exposure information: To maintain compliance with FCC RF exposure requirements, use the product that maintain a 20cm separation distance between the user's body and the host. This device is intended only for OEM integrators under the following conditions: The antenna must be installed such that 20 cm is maintained between the antenna and users. The transmitter module may not be co-located with any other transmitter or antenna. As long as the two conditions above are met, additional transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required for the installed module. Important Note: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the Federal Communications Commission of the U.S. Government (FCC) is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator shall be responsible for re-evaluating the end-product (including the transmitter) and obtaining a separate FCC and IC authorization in the U.S. and Canada. OEM Integrators -End Product Labeling Considerations: This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following:"Contains, FCC ID: 2AD66-1276-C1. The grantee's FCC ID can be used only when all FCCcompliance requirements are met. NiceRF Wireless Technology Co., Ltd. sales@nicerf.com Rev 1.1 - 10 - www.nicerf.com LoRa1276-c1-915 OEM Integrators -End Product Manual Provided to the End User: The OEM integrator shall not provide information to the end user regarding how to install or remove this RF module in end product user manual. The end user manual must include all required regulatory informationand warnings as outlined in this document. NiceRF Wireless Technology Co., Ltd. sales@nicerf.com Rev 1.1 - 11 -
