Speedybee question

I recently got a second hand ZOHD dart 250g. Speedybee easy fly FC. Haven’t gotten it up in the air yet.

Is it compatible with the original DJI 01 air unit? The super fat bulky one. I read that it might need soldering but don’t have anything solid. I’ll attach some images.

I tried connecting it with the plastic connector but it doesn’t seem to work.

More work involved than just plugging it in, hopefully you haven’t fried it

Have a look at this

i don’t smell anything or see anything, so i don’t think i fried it

man i wish someone was nearby to help

Can you find the FC wiring diagram? Had a quick search but not obvious which one you have.
With it we should be able to confirm if a re-pin of the cable is an option.

I use a speedybee with the original Dji Au. 100% compatible. Use the speedybee plug and solder to the Au harness. +V Red. Grey And white are video signal to FC. Connect Tx To Rx on the uart. Yes they reverse. No damage if you do that part wrong. Just won’t work. The Yellow wire is not used. It is the control link wire if using a Dji Tx. Black and Brown to ground on FC. The Brown wire appears to make little difference if not connected, but officially it should be.
