I am super excited to finally get to play with the Piggy OSDs from Banggood since so far I only had the original HUGE minimOSD to test the RFOSD FW on ๐Ÿ˜ฎ

This is how I ended up enjoying it!

But first let’s check how the Piggy looks and how it fits on the “HS1177 style” cam… in this case it’s a swift 1 which makes it a bit more difficult to fit since the S1 uses different screws (smaller) and therefore it isn’t a perfect match… but doable… you will see ๐Ÿ™‚

Drops in nicely but you can notice that the screw holes don’t line up perfectly ๐Ÿ™

..and the short “stock” screws don’t allow for letting it screw on loosely…

so I made some holes with my soldering iron in it to gain some millimeters ๐Ÿ™‚

added the pins and soldered the original connector to the OSD…

screwed on the lid… and noticed I forgot the Rx wire lol… (connecting Rx on the Piggy to Tx4 on the Revolt)

make sure you get your connector right… 5v isn’t in the middle anymore like most of the time with “servo connectors”

last test before I mount it inside the canopy…

Don’t get confused with that white wire, had no other colored wire laying around… that one on Rx3 is for SmartAudio, the white one from the Piggy Tx pad is going to the bottom of the revolt and it’s Tx4 pad ๐Ÿ™‚

Super happy with the Unify… just a bit said it doesn’t do audio… (easily with SA)

and again a look at the final setup ๐Ÿ™‚

What I learned from this build is that I will be using a 90ยฐ connector next time… like this it’s limiting my cam angle (connector will touch FC) but not enough for me to “redo it” ๐Ÿ˜‰
Other than that I hope “remaiden” will go well though I have high hopes the Unify will handle the additional current draw like a champ!

Unboxing the PiggyOSD:

Flashing RFOSD FW:

Setup in RF1:
set telem_rfosd=4 (Tx4 pad on the bottom pad)
set adc_current_factor=0 (I have no current sensor connected so I set it to 0 which will 0 out in the OSD instead of going nuts)

 

Swift 2 with PiggyOSD (MinimOSD)

After the success with the Swift 1 I had to try it with the Swift 2, this time I wanted to make one “connector” for all:

Rx / Audio / 5V / GND / VI_O

That’s how I did it ๐Ÿ™‚

and a look at the other side ๐Ÿ™‚

and from the top ๐Ÿ˜‰

With the Swift 2 the screws and the screw holes are a perfect match, could even use the stock screws to mount the Piggy on the top of the back plate ๐Ÿ™‚

Everything is super tight and I had to shorten the “pins” for the cam osd connector (made sure I disabled cam osd before that though I think it would still work) and made the cam connector (with audio) a bit smaller but cutting off the right “ear” next to the audio wire…

All in all, maybe even easier then what I did with the V1 :popcorn:

This is the SPMFC F400 running RF1 hocked up to a MicroMinimOSDย flashed with RFOSD and an IRC Trampย connected to a Swift 2 ๐Ÿ™‚

The MicroMinimOSD is powered by the PDB’s 5V out but since the F400 has it’s own 5V reg it sure could power that OSD as well^^
Another cool thing with this combo is that the Tramp supports both TLM and audio at the same time without any mods, so we are taking advantage of the build in mic of the Swift 2 here.

Now it gets kind of confusing with the F400… as of right now (RC18 / 300) you hook the Tramp TLM or Unify SA up to Tx4 and the OSD to Tx2 but in the CLI those are the right commands to get it working:

// RFOSD + Tramp
set telem_rfosd=2
set telem_tramp=3
save

// RFOSD + Unify
set telem_rfosd=2
set telem_smartaudio=4
save

power cycle and you should be able to control the vTx via your transmitter and see the RFOSD in your FPV feed ๐Ÿ™‚

F400 and PiggyOSD

BTW: There is a Matek PDB with a 0-3.3V current sensor on bangggod which I ordered and am going to hook up to my revolt to test the “current” OSD part ๐Ÿ™‚
