Nürnberg Toy Fair 2014: New Devo 12E, Devo F12 FPV

I hope they don't charge much of a premium for the 12E. Looks like a Devo10 with 2 more knobs. Probably costs all of $1 more to manufacture.

the 2x3 mod for the 7e can be added to the devo8 or devo10 as well.
We'd need to figure out which connections to make, and the code would be updated, but it will work on any of the Walkera Txs.

It is unlikely I'll be willing to buy a 12E just to try to figure out the differences from the Devo10, so if it is wired differently, it may take some time to make work.

The devo8 and devo6 modifications should be the same, since they both have the same matrix (devo6 just doesn't have upper trims)

For the Devo8, I think you want to connect the outside poles of the switches to B6 B7 B8 B9 (look at the Devo8 pinout article to hcoose good connection points)
the center terminals will connect to E2

For the Devo10, it should be B4, B5, B8, B9 and center to E2

For the Devo12, it should be C6 C7 C8 C9, and center to B5

However, to maximize flexibility, we could flip the matrix, and you could have 5 switch positions rather than just 4. I'm really not sure it is worth the effort, but for example on the Devo8, you'd choose to connect to E2, E3, E4, E5, E6 with center positions to B6.

I am not going to support both orientations, so whichever is chosen now will be the end of it. i haven't looked at the matrix wiring. It is possible wiring one way is easier than the other.

Note that the above is based on my tables, and has in no way been tested.
