DJI Osmo FrameTap Appears in FCC Filing

A quiet FCC filing has revealed a DJI product name that absolutely nobody had on their 2025 bingo card: Osmo FrameTap. The discovery came courtesy of a tweet by drone sleuth @Saracool_drone, who spotted a freshly registered DJI device hiding in plain sight inside the FCC database, dated December 17, 2025.

Naturally, this sent me digging.

I am Rafael, writer at DroneXL, professional DJI overthinker, and part time FCC document archaeologist. What I found raises more questions than answers, and some of them are very interesting.

A strange name with a familiar number

The FCC filing lists the product as Osmo FrameTap, model number RC508. That model number immediately rang a bell, because DJI recently registered the Osmo Mobile 8 Pro under the model name DS508.

RC508 and DS508. Two letters difference. Same numbers. Coincidence? Possibly. Typical DJI internal naming symmetry? Very likely.

The FCC test report confirms this device is a standalone product, but here’s where things start to get spicy. In the “support units” section of the testing documents, DJI clearly states that the Osmo FrameTap was tested together with the Osmo Mobile 8 Pro and the HUAWEI NOVA 8 5G android Phone.

Something that keeps me thinking is that the test was made with a cell phone from 2021. In this age, 2021 feels like prehistoric times. Specially if we are talking about DJI.

That is not something you do with a random, unrelated gadget.

FCC documents reveal how it connects

While DJI requested confidentiality for photos, schematics, and internal designs, the FCC paperwork still reveals some useful technical clues.

The Osmo FrameTap uses Wi Fi in the 2.4 GHz and 5.8 GHz bands, alongside Bluetooth connectivity. Antenna gain sits around 1.7 dBi, and the internal antenna design matches what DJI typically uses for compact accessories rather than full featured standalone devices.

In short, this thing talks wirelessly, and it talks a lot.

That rules out passive accessories and points toward something active, smart, and tightly integrated with another device. And since it was tested with the Osmo Mobile 8 Pro, the picture starts forming whether DJI wants it to or not.

An accessory hiding in plain sight

The name Osmo FrameTap feels like a hint rather than a label. Frame. Tap. Those words suggest interaction, known moments, markers, or control. This does not feel like a new gimbal, camera, or phone mount.

Instead, all signs point toward an accessory designed to enhance how the Osmo Mobile 8 Pro works. Possibly something that interacts with framing, gestures, tracking, or even live controls during filming.

To be clear, we do not know exactly what this device does. DJI has locked down the visuals, and the FCC documents stay firmly on the technical side. But between the naming, the wireless stack, and the testing setup, it looks far more like a companion product than a standalone star.

And if history tells us anything, DJI loves quietly building ecosystems around products you already own.

DroneXL’s Take

DJI rarely files things by accident, and they definitely do not test unrelated products together for fun. The Osmo FrameTap feels like an accessory waiting for a launch window, not a mystery product destined for the drawer.

The RC508 and DS508 naming alignment alone is enough to raise an eyebrow, and the wireless capabilities suggest something interactive, not decorative. This investigation is just getting started, but one thing is clear: DJI is cooking something for the Osmo Mobile 8 Pro, and they forgot to turn off the FCC stove.
