The m128 doubles the flash memory and eeprom memory of the m64 chip.
The m2561 also doubles the RAM memory. This alone makes it much better..

João

I think that at least the m2561 version could behave quite similar to the other (more powerful) boards.

João

This looks quite similar to what was done here:

https://openrcforums.com/forum/viewtopi ... =84&t=7299

At least the idea looks similar

João

I think this GREEN chip thingy might not be an 100% clone of the m128, and that might be the problem.

João

Hmm, can't see the connections and the cuts very well. Also what Mosfet arte you using?
On the board that doesn't work, make sure the Mosfet tab is not touching the ground plane just under it.

João

Check that the telemetry programming on your model didn't change, and has the correct fields selected.

João

I believe I connected the internal module's telemetry to COM 2.

Thanks Mike..

João

Mike, you still do wonders with the stock 9x radio after all these years.. Unbelievable. Thank you

João

Thank you, I guess I will have to update my multi modules to the latest then
I am normally quite afraid to do that, specially in the middle of the season

João

Mike, would it be possible to have the scanner on the other older boards? AR9x, 9Xtreme, etc? Thanks.

João

I don't know that receiver, but I would start by making sure the antenna(s) is/are not broken. Then inspect the PCB looking for bad soldering or shorts.

João

On the 9xtreme use the diode exactly as shown on the 9xtreme mods thread.. Not the Mosfet..

The 9xtreme has a complete different power circuit.

João

A forum user is making a few 9xtreme boards..

Yep, CPU dead, I have one of those radios from a friend here at home with the same problem. Will attempt to replace the CPU as well, when I have some spare time

João

Mike, can't it be done using a GVAR?

João

I have just seen your post. Sorry. I have an AR9x radio with a multi Module inside....
Also have a 9x radio with a 9xtreme board with a Multi module installed inside.

João

Yes, I have an AR9x radio currently in working order.. But it has a Frsky DHT module inside, not a MUltiProtocol module.
My other AR9x radio that has a Multi module, broke the little battery connector. Need to fix that

João

Nice that you found it.. Well done

João

So, the last example worked for you? did you try it?

João

The answer to your question is, there is probably a simple way, but we need more information please.. What exactly do you want to do?

Simple is relative by the way What is simple for me might not be for you

João

The loss of control is probably caused by the RF module. You'd probably better buying a better one. Try Frsky. A bit more expensive but much more reliable.
Yes, you can (and should) update the radio's firmware, but I think it won't fix that problem. as I said, the problem might be the module.

João

Hello, im not sure if this is normal in erskyTx but on OpenTx this is not happen. When i turn off Tx and turn it on back, ten throttle is pushed for about half second, it is very scary with mounted props. My radio is 9XR Pro with erskyTx 222 EDIT: when i disable (uncheck) Fix Offset in Mixer then t...

My concern was whether the charging function would still work with the MOSFET in that position. Yes, it will because it will polarize the Mosfet normally with the positive entering the source, but it will blow if the charger is reversed, that is why i suggested a protection on the charging circuit....

Hang on, I'm not sure the diagram from João is correct. The gate is OK, but I would put the drain to the right of the existing cut (to the switch) and the source to the track leading the the connector (pin 3). Mike Mike, I think the connections I posted are correct.. The Mosfet should be a P-Channe...

As far as I understand it, I would do it like this on an original Turnigy 9x board without upgrade boards.
Mike, does this look right?

Thanks

João

EDIT: And perhaps I would put another one on the Charging circuit too.

I would think about that carefully For example, what features are currently limited due to RAM compared to the other processors?

João

Mike, isn't that bad for the m64?

João

Mike, what about using Eepe / Eepskye and an FTDI to flash it?

João

The Arduvoice connects to other pins of the processor. The pins where the left vertical stick's trims are connected originally.
These are then moved to the ArduVoice board.
