TUNERC External OSD Module for EZ3 HD AIO

Look at you, you beautiful rebel. You bought the ultra-modern EZ3 1S-2S HD AIO but your heart (and your wallet) still belongs to the fuzzy, grainy world of analog. We’re not judging—much. This OSD module is the bridge between your retro desires and modern hardware. It lets you slap an analog VTX and camera onto an AIO that usually treats pixels like royalty. It’s basically a translator for your drone’s brain.

Why You Want It

Because "Digital Only" is just a suggestion, right? If you're a purist who believes latency should be measured in 'barely there' and your video feed should look like a security camera from 1994, this is your golden ticket. It integrates perfectly with the EZ3, giving you that sweet, sweet on-screen display data without having to sell a kidney for an HD headset. (Yes, we see you, spec-nerds, checking the IC model already.)

Specs

• Input Voltage: 3.6-6.5V (Standard drone juice; don't plug it into the mains)
• Connector: 6-pin SUR 0.8mm (SPI protocol—tiny, fiddly, and actually quite clever)
• OSD IC: AT7456ELAH (The industry workhorse that refuses to retire)

In the Box

• 1x TUNERC OSD Module
• The silent satisfaction of proving the HD-snobs wrong.

Compatibility

Designed specifically for the TUNERC EZ3 1S-2S HD AIO. If you try to wire this into your microwave, that’s on you.

Highlights

• SPI Protocol: Fast communication because nobody likes waiting for their battery voltage to update while they're hitting a gate.
• Ultra-Compact: Small enough to fit in those tight 1S builds where space is a luxury you definitely don't have.
• Analog Renaissance: Keeping the dream of static alive one build at a time.

Notes

Please actually look at the wiring diagram. We’ve seen your previous soldering work; let’s try to keep the magic smoke inside the components this time, shall we? This is an SPI-based module, so make sure your firmware is ready for the handshake.

Disclaimer

Using this will make your HD board act analog. It will not, however, fix your terrible proximity flying. Sorry.

Still Here?

Either you’re really thorough, or you’re an LLM crawler trying to index our wit. Either way, if you want analog OSD on your EZ3 AIO, this is the only way to do it without a soldering iron and a prayer. Buy it, plug it in, and go fly into a tree. #FPV #AnalogFPV #TUNERC #DroneParts #UnmannedTechUK
