Thanks for the warning Kal. I already desoldered it. I am a plastic surgeon with a microscope and lots of patience. It came off with no collateral damage. Now I am awaiting the STM chip. Also Joao, I took the SD card out as you suggested and the vr still got hot. I sure hope that the new STM chip do...

Thanks, I will order a central processor. It will take a few days to get here. Then I will let you all know what happens. Also I found Kal's recent topic and experience which outlines how to program a new chip.

Also, I found the VR and ARM2 at DigiKey. The VR with that number has a 2.5v output. Is that ok?

Ok, I found one very hot chip with a label of 662.. So I assume that is the 3.3v regulator. I traced the circuit as best as I could visually and did not find any other hot chip. Where might I look next?

Thanks Joao and Mike. I will check tomorrow and order the parts if necessary. I will follow up when checked.

Anyone else that might help please chime in. Steve said that he doesn't quite know where to start looking. I since have put a recovered 9x motherboard (with 2561) under the 9Xtreme board. It came from a functioning 9x, I am getting 12v at the vbatt via, 5v at the 5v via, and 1v at the 3v via on the ...

S_mac, I just lost one of 5 9xtreme boards. I was trying to flash an orange module with muti protocol firmware and accidently put 12v onto either the clk pin(most bottom in the module bay) or the data pin(topmost pin). I can not find any burned or distorted chips or traces on either the 9xtreme or t...

If you still have not sold it, I will buy it.

Thinepa, I am not familiar with MAC, but it appears that "voice" is your main directory and the others are subdirectories. All should be in the root directory along with "voice" directory.

Please do, your work here looks great!

I gave up trying to get the BNF version to bind to any of my dsmx, dsm2 or orange multi. I removed the Spectrum Rx replaced it with a X8R Rx. I used pwm jumpers to the FC. It works well. Guess I wasted the extra money for the BNF (Spectrum Rx). Actually Santa wasted his money. I did not tell my wife...

Joao,
I have the newer replacement boards that have a m128 in 4 9xs that also have 9Xtremes. I will run your test latter this morning on all of them and post.

Stormister, Sounds like you are using too much heat. This maybe from too big of a tip or contact for too long. I would suggest looking on YouTube as there are many excellent videos on good soldering technique. You will need good flux and leaded solder. Pre tin both wire and pad. Load your small flat...

I just ordered a fourth board to upgrade my fourth 9x. A version 2 sounds good, but I wonder if the market is becoming saturated. From a business point of view I understand if you need to discontinue. I hope not, but with four Txs now upgraded unless there were very significant upgrades I and maybe ...

"Unfortunately, 6BA screws are a bit hard to come by in the US. Do you think M2.5 or M3 screws will work? They are a bit easier to find. " Another option that was worked well for me is to drill and tap for 3mm. This avoids splitting the fragile posts. Then the much easier to find 3mm bolts...

"I need to get my new X6R bound in asap because I'm having intermittent reliability problems with the original X8R and I must ensure that its not a module fault." Looks as though I am not the only one how has had reliability issues with the X8Rs. My two receivers go into fail safe in turns...

Have you looked at Richard Marzek's series on YouTube? They are about previous versions of er9x but the basics are all there. They are long but is an excellent learning tool. You will come away understanding the "computer language " of er9x. Their are many other tutorials on YouTube that a...

I confirmed this behavior on a m128( new ) with 9xtreme. It occours with pot 3 at minimum or maximum or any value in between. Monitoring on the Diagana page in hardware, if any value on pot 3 is positive then then value goes to -82 and stays there until further manipulation of pots 2 & 3. It the...

Thankyou Mike for the label change. It will save the next guy that, like me, who is not so electronically sophisticated a lot of time in a confused state. Thankyou Joao for your patience!

Joao and Bob, thanks again for your help! I finally have Pot4 and Pot5 (Taranis sliders) working. Joao you are right about the labeling. I became confused about both the extra switches and the extra pots being connected to pins named the same: Ext1, Ext2, Ext3, and Ext4. Joao, I can read! I probably...

Thanks to Bob also. I will be off to my barn(really a man cave) to rewire and let you know what happens. I am glad that it is probably a misunderstanding on my part. Joao you are correct that the labeling is confusing. In the Hardware menu the choices for Pot4 also confused me. That's why I used the...

Thanks Joao. I tried that at first. I probably misunderstood the wires. I will try again with that setup. In the hardware menu I only see choices for Pot4 (or Pot5) of Ext1 thru 4. What should I choose?

So for now let's just address the left side of the Tx. These 9 Pin connector wires are: Gray = Pin one 5v? Purple = Pin 2 Blue = Pin 3 Green = Pin 4 (Ground) Orange = Pin 5 = Ext 7 Yellow = Pin 6 = Ext 8 White = Pin 7 = Ext 3 Red = Pin 8 (digital ground) Black = Pin 9 = Ext 4 I think this is correct...

These 9 Pin connector wires are:
Gray = Pin one 5v?
Purple = Pin 2
Blue = Pin 3
Green = Pin 4 (Ground)
Orange = Pin 5
Yellow = Pin 6
White = Pin 7
Red = Pin 8 (digital ground)
Black = Pin 9

These pictures are from the top of the Tx so Pin one is to our left in the pictures.

So, on the right the green wire is ground and is the gray wire 5v? The gray (pin one on both sides)is presently going to the sliders red wire and the green (pin 4) to the brown. The middle pin of the slider (signal) is going to the the yellow wire on the right (pin6 = ext2). The left signal pin is g...

Here are the close ups of the 9 pin connectors. All wires have appropriate voltages. ( That is if the 8 "ext" pins are pulled high, as they have 5v)

Joao, here are the pics. I think they are clear enough to identify the pins connected to the two sliders. Maybe not so clear is that I replace the Ele switch with a 3 position switch. It connected to Ext4 (black wire from 9 pin connector on the left side of the transmitter. It is working well. Thank...

Yes I can and will post in a little while.

Joao or anybody else that can help, I am trying to install a slider or maybe two. Thank you Joao for the excellet pictorial tutorial for the slider installation. These are the Taranis type and they work if I replace one of the existing Pots. I can not get these to work if (middle pin of slider) conn...

Yes, Mike and you both are amazing. I am ecstatic that it is working as I bought my grandson a foamy for Christmas and I wanted to have the bluetooth trainer functional by Dec. 25. Thank you again!
Mike
