please show in the image which component should I jumper & which component should I replace.
thanks.

Devo8 power circuit:

what about the voltage regulator devo F12E.
my devo f12e was totally dead due to a wrong plug + - battery. please help me resolve this problem
thank you
regards

This is my installation method including power supply mode, I have not found any problems at present.

This is my test module. www.deviationtx.com/forum/3-feedback-que...evo-f12e-fpv-problem

I think you should successfully replace the original 5.8G module, this is my test module. JM201R(32CHANNEL) [attachment=11822]

The F12E and AUX7 built every night also have this problem. Manually modify the tx.ini file to work properly.

Hi Folks,

recently I got a used Devo F12E for a very reasonable price of 50€. I did the XMS Mod with the 4MB Flash and inserted 4 in 1 Module to fly with my FrSky XM+ Receivers.

Unfortunately I'm not that familar with Deviation yet, has someone a Working Config for Betaflight / Cleanflight? Any feedback would be appreciated.

Thats excellent information. Thank you. I will soon have an AV status light then and while im there i will try to trace the other led and see if it has a function we can use thank you again 52dgj

Yes, you can add an AV status light,You turn on the 5.8G image, the LED in the red position will light up.

Were it not for your stl this wouldent exist. So the good job goes to you sir.

Haha just figured out that you have remixed my original design. Good job!

I made my original design with Blender, maybe I will upload the original file to thingiverse as well.

You need flash updated DFU and update filesystem files.

XMS files are for modded transmitter with bigger flash memory chip (USB drive). You can read about it:
www.deviationtx.com/forum/builds/6861-ul...-devof12e-xms-builds

devo12-XMS version don't use DFU library and all filesystem files placed on USB drive, as for devo8.

Not sure all i know is i tried it with undesirable unusable results using the power and ground from the 12v out to a lm2596 buck converter.

Thank you again for sharing.

It really sounds strange that the 12v port does not work, as I guess it is intended for this? Could the reason be grounding problems (several grounds over different currents???

The picture for internal installation shows the correct places to wire to the trainer plug.

Do not take power from the 12v out at the top. The processor will slow down. everything will be delayed or just not work voice takes extra 5 seconds and may not play at all been there done that not a good power source. I listed the two options those are the choices i am aware of

There is no existing speaker under the grill just an empty hole. Yes its safe to renove the board but there is no need. just take out enof screws to make room to slide the speaker under

Thanks for the info.

I haven't checked the trainer port on the F12e yet, but assuming it is the same solder points as the devo 10, I know where to tap into that one. For power, I was thinking about using the external power plug at the top of the transmitter. That is labeled 12v, and should be perfect for a 12-5v step down. -Given that is it made for external devices, it should be a good place to draw power.

-And the loudspeaker; Did you replace the existing one under the grille in the front? Is is 'save' to remove the circuit board covering it. I guess all the buttons contact that board?

I took ppm output from "the trainer on when unplugged" picture from the guide for voice module. As for power 2 choices i can think of
1. Seperate power for dfplayer

2. A pololu stepdown converter powered off the battery. With the enable pin hooked to anywhere live wile power is on. This is what im told but i havent finnished yet due to dfplayer doing matrix voice now that its getting 5v and havent picked up the propper adjustable pololu

Just a note. When selecting the speaker there is at least 3 mm of extra room for a bigger speaker. Measure twice fit once. Assume its all the same and use glue. Ask me how i know lol.

Hi
I have two Devo 10 and two F12e. I have tx modded all, but voice only on one of the 10's, and I see the same bug when exiting a model that use the trainer port for input. I have to deselect ppm input, and then select another model. Othwerwise, the transmitter will reboot.

This is probably a bug, but I can live with it. I have not seen voice setup being affected on the Devo 10 when this happens. I am considering doing the voice mod on the F12e, because it really works well for me on the devo 10. Any suggestion on where to look for soldering options on the F12e?
