Module Mechanical Integration The SkydioLink Dual Band module snaps into place using the two board to board connectors (Hirose DF30FC-40DP-0.4V) on the lower side of the module. When installing the module, it is important to ensure that the technician using ESD protection On the end device, the spacing and board to board MPN must match the module side specications:
Mating board to board type: DF30FC-40DS-0.4V Mating Board to board spacing: 38.44mm Antenna Connectors The radio module uses two I-PEX u.FL connectors (20441-001E-01) to connect external antennas to the module. The connectors are snapped in place, and do not require any external pressure or screws. On the antenna cable, the mating connector is an I-PEX 20351-1 series (or equivalent) connector. Antenna types and gains must follow the FCC / IC regulatory lings submitted by Skydio. Thermal Management In order to prevent overheating when operating at high power levels, it is important to move heat out of the module. It is recommended to heat sink via the shield can on the top of the module, which has a direct thermal interface to the radio & front end module components that generate the most heat. An example of this is shown below on the Skydio X2 UAV, using a graphite strap to move heat from the module to the UAV chassis. Usage Guidelines Power & frequency settings are not advised to be exposed to the user, and should be set at the factory to ensure that the module is correctly congured relative to the regulatory lings submitted by Skydio. Host Device Requirements This module should only be used in pre-approved Skydio host devices. Any additional host devices must go through an approval process completed by Skydio. This module should only be used in pre-approved antennas. Any additional host devices must go through an approval process completed by Skydio. The host product needs to provide a physical or e-label per FCC KDB 784748. All standalone modules without an integrated display on the module must be labeled with the modules FCC ID. Only modules with a display can use e-labeling (see also KDB Publication 784748 D02). A host product shall use a physical label stating Contains Transmitter Module FCC ID: 2ATQRSMODBV1, or shall use e-labeling. When integrating the module into a host device, the separation distance between the user and the host device must be >20cm. If the separation distance is less than 20cm, additional testing must be performed to ensure compliance for RF exposure. Skydio has approved use of the below host devices with their respective antennas for this radio module:
Skydio Enterprise Controller (C78) Skydio X2 UAV
(R21) Skydio Dock
(G27) Skydio 2+ (R35) Regional Settings All power levels & frequency bands must follow regional restrictions. Two methods can be used to ensure that these are followed:
1. During a factory installation, set the power tables based on the intended country of sale for the specic end device SKU 2. Use GPS data from the host device to select a specic power table to be referenced. This is recommended for devices that are portable. Note that the end device ultimately controls power levels, frequency band and other radio settings and it is up to the end device manufacturer to ensure compliance with existing lings for this module. Mechanical Requirements Compliance Information FCC Any changes or modications to this equipment not expressly approved by Skydio for compliance will void the users authorization to operate this equipment. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. 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. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. The distance between user and products should be no less than 20cm. The end user must follow the specic operating instruction for satisfying RF exposure compliance. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. IC The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF eld in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable from Heath Canadas website www.hc-sc.gc.ca/rpb This device contains license-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canadas license-exempt RSS(s). Operation is subject to the following two conditions:
This device may not cause interference. This device must accept any interference, including interference that may cause undesired operation of the device. L'installateur de cet quipement radio doit s'assurer que l'antenne est situe ou pointe de manire ne pas mettre de champ RF au-del des limites donnes par Sant Canada pour la population gnrale; consultez le Code de scurit 6, disponible sur le site Web de Sant Canada www.hc-sc.gc.ca/rpb. Lmetteur exempt de licence contenu dans le prsent appareil est conforme aux CNR dInnovation, Sciences et Dveloppement conomique Canada applicables aux appareils radio exempts de licence. Lexploitation est autorise aux deux conditions suivantes :
Lappareil ne doit pas produire de brouillage;
Lappareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible den compromettre le fonctionnement.
