FAQ
What is the EMAX Aeris Link?
The EMAX Aeris Link is an external ExpressLRS RF transmitter-module series designed to add an ELRS control link to compatible radio controllers.
Is the Aeris Link an FPV video transmitter?
No. It transmits radio-control and telemetry data between a compatible radio controller and an ExpressLRS receiver. It does not transmit camera video.
What is the difference between the TX and Micro versions?
The full-size Aeris Link TX fits compatible JR-style module bays and includes an OLED display. The Aeris Link Micro fits compatible Nano-style module bays.
Which frequency versions are available?
The series is available in 2.4GHz and 915MHz versions, with 868MHz operation used for compatible EU regional configurations.
What is the maximum output power?
The 2.4GHz version supports up to 1000mW, while the 915MHz version supports up to 2000mW.
Can the output power be adjusted?
Yes. Multiple output levels are available from 10mW up to the maximum supported by the selected frequency version.
What power input does the module support?
The XT30 external-power input supports 5–21V. A 2S battery at approximately 8.4V is recommended by the product documentation.
Does the module have a cooling fan?
Yes. The integrated fan helps manage temperature during high-power operation, and its activation threshold can be adjusted.
Is an ExpressLRS receiver included?
The standard transmitter-module package contains the selected module and matching antenna. Aircraft-side ExpressLRS receivers are separate product options unless specifically included by the seller.
How is the module configured?
Compatible settings can be managed through an ExpressLRS LUA script on the radio controller. Wi-Fi mode is also available for supported firmware management.
Can the module be powered without an antenna?
No. Install the correct frequency-matched antenna before powering the module to reduce the risk of RF hardware damage.
Does high-power operation require external power?
External power through the XT30 input is recommended during high-output operation to prevent insufficient power from the radio controller.
B2B Procurement FAQ
Which Aeris Link version should be selected?
Buyers should confirm the radio-controller module-bay size, required operating frequency, regional frequency regulations and required maximum RF output before selecting a version.
What should buyers confirm before ordering?
Confirm the JR or Nano module interface, 2.4GHz or 915MHz frequency, antenna type, firmware version, receiver compatibility, external-power requirements and package contents.
What information should be included in a bulk RFQ?
Include the required quantity, selected frequency, module-bay format, destination country, preferred firmware, receiver requirements, packaging needs and requested delivery schedule.
Are ExpressLRS receivers included with the module?
Receivers are normally separate product options unless a specific package states otherwise. Buyers should list the required receiver quantity and antenna version in the RFQ.
Can 915MHz products be supplied for every country?
Frequency and output-power regulations vary by market. Buyers must confirm whether 915MHz FCC, 868MHz EU or another permitted configuration is required.
What quality checks are recommended before shipment?
Recommended checks include module power-up, fan operation, antenna inspection, frequency and output verification, CRSF communication, binding, telemetry, USB connectivity and external-power testing.
Can packaging and module combinations be customized?
Packaging, labeling, antennas, receiver combinations and documentation may be customized depending on supplier capability, order quantity and regulatory requirements.
Which documents should bulk buyers request?
Buyers should request the latest specification sheet, firmware information, user manual, packing list, frequency declaration and applicable compliance documents for the destination market.
