-40C to +85C Operation 1.8v to 3.6v Operation RoHS Compliant FCC/IC/CE/MIC Certified DESCRIPTION Tango Sky is a low power, high over the air data rate, worldwide FCC/IC/CE/MIC certified 2.4GHz RF Module with a 100mW PA/LNA for extended range operations. Tango Sky is based on the Nordic nRF24L01+ radio incorporating an Enhanced ShockBurst hardware protocol accelerator which offloads time critical protocol functions from the application microcontroller enabling the implementation of advanced and robust wireless connectivity with low cost 3rd-party microcontrollers. Tango can be used with the nRFgo SDK for easy code development. The nRFgo SDK is a fully featured Software Development Kit for Nordic nRF24L Series 2.4GHz RF System-on-Chips (SoCs). Used in conjunction with the nRFgo Starter Kit and nRFgo Studio, it contains everything needed for code development and debugging, including integration with Keil Vision IDE, a comprehensive library of hardware abstraction layers (HAL), Nordic Gazell 2.4GHz RF protocol stack, USB stack, and example applications. The module brings out all the functional pins of the nRF24L01+ and PA for maximum usability and flexibility including:

+20dBm Tango SkyINDUSTRIAL RADIOTRANSCEIVERMODULE DATASHEET Input excel file FCC OPERATING NOTES Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. 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 instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does 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. 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.
