Hollyland Spares - HDMI Male to Male Cable (for Mars Series)

The Hollyland HDMI Male to Male Cable (Model: HL-HD03) is an official factory-spare video data interface cord engineered to deliver high-bandwidth digital signals within the Mars and Cosmo wireless ecosystems.

On a production set, standard consumer HDMI cords are often too thick, stiff, or long, leaving loops of excess wire that catch on equipment and disrupt the balance of handheld rigs. This OEM cable features a slim, highly flexible profile that is explicitly tailored for on-camera rigging, bridging the connection between your camera body, video monitor, and wireless transmitter without unnecessary clutter.

Core Hardware & Signal Features

• High-Bandwidth Digital Transfer: Designed to meet high-definition standards, passing video data up to 4K resolution at 30 frames per second or 1080p up to 60 frames per second cleanly. It prevents signal dropping or digital artifact lines from interrupting your real-time wireless monitoring stream.

• Gold-Plated Type-A Terminals: Features full-sized, standard HDMI Type-A male connectors on both ends. The premium gold-plating finish ensures high conductivity, resists oxide corrosion over prolonged field use, and minimizes electrical contact resistance.

• Ultra-Slim and Flexible Layout: The cable insulation is engineered with a thin, pliable outer jacket. This makes it incredibly easy to shape around camera cages, route through tight accessory setups, or manage on sensitive motorized stabilizer gimbals where thick cables pull against the balancing motors.

• Molded Strain-Relief Boots: Both terminal housings feature integrated structural strain-relief collars. This architecture absorbs bending forces directly at the cable-to-plug transition point, preventing internal micro-wire fracturing when the camera setup undergoes sudden motion.

System Interoperability

This universal video interconnect links any full-sized standard HDMI source directly to your hardware infrastructure, and is explicitly matched with:

On-Set Cable Management Checklist

When securing this HDMI cable between your camera and the Mars transmitter, try to leave a tiny bit of slack right before the wire meets the camera port. HDMI connections do not feature mechanical locks like SDI cables do, meaning sudden tugs or heavy pressure can easily damage the internal contact tongue or work the cable loose mid-take, cutting off your remote video feed completely. For maximum safety, anchor the cable down with a dedicated small cable clamp on your camera cage.
