Hi,

I read a lot of threads here about the P3 flat "con board / main board" ribbon cable.
It's a very sensible cable that you can damage when your open or the RC or manipulate it with a pliers.

I damaged mine when I installed the DBS mod (topic here : iPad not recognized after DBS itelite mod)

As this piece is not sold by BJI, I wanted to share here how to replace the ribbon.

Step 1 : Find a new ribbon

Good news, the DJI ribbon has a strange shape, but it's a regular 1-1 ribbon cable !
- Pitch : 0.5mm
- 32 circuits
- 6cm long
- same side connectors

I easily find ribbons with the same pitch but 32 circuits seems not to be standard...
I order a 40 circuits cable here : 15166-0435 | Câble en nappe, 40 voies, pas de 0,5mm, 0.152m | Molex
(French eletronics online retailer as I live in Paris, France)

Cables are sold by pack of 5. (trust me 5 cable is ok, see step 2!)

Step 2 : Cut extra cirtuits
This is the very tricky part. Take your time ! I succeded in after two trials.
I trimmed it using a cutter with a fresh blade.

Step 3 : Replace the damaged ribbon

It works perfectly now :)

I hope this helps !

For anyone interested, I just received ribbon cables (32 pins) that perfectly fit the remote. I broke off mine while installing a DBS Mod. Will be happy to sell one and send it.

Send me a DM.

And what about the connector? I'm afraid I damaged it while was opening my rc. It doesn't hold the flat anymore. It doesn't seem a common one. Where can I find it?

Hi old thread but hopefully someone can help, it looks like the original cable is fitted with the white spot opposite to the spot on the pcb (both main pcb and connection pcb) when i did a continuity check on my ribbon cable (disconected) there appears to be several cross connections,so just wondering how a straight through cable replacement works ?
my phone is not being seen by the GL300B having just received a replacement USB pcb so desberate measures
