===== Devo 7E =====
{{:hardware:devo7e:walkera-devo-7e.jpg?nolink}}

The Devo 7E is the best value for money transmitter that you can buy that DeviationTx supports. It shares the same smaller body as the Devo 6 but instead has a 128x64 pixel LCD screen similar to the Devo 10.

It however only has 128k of flash memory, which is barely sufficient for DeviationTx. It is equipped with only two 2-way switches and a range limited RF module. There are proven modification though to overcome these limitations.

==== Installing DeviationTx ====
Start by reading the Devo 7E [[https://www.deviationtx.com/user-manual/user-manual-7e-10|manual]].

If that's not enough, the tutorials below should get you going.

==== Modifications ====
Due to its' popularity and price, the Devo 7E probably has the most documented modifications available within the Walkera Devo line of transmitters. Here you'll find the tutorials and videos to get you started.

== Disassembly ==
All modifications have to begin with disassembling the transmitter. Here's how to do it.

== Extra RF Modules ==
You can install up to 3 extra RF modules in the Devo 7E, for a total of 4 modules including the stock RF module. Two quite easily and the third via soldering directly to a processor pin.

Alternatively you can [[:building_the_multi-module|build]] the [[modulelist:multimod|MultiModule]] instead. With the MultiModule, you will not need to solder to the processor pin and still use all 4 modules.

The process is very well documented in the wiki page "[[:rf_module_installation|RF Module Installation]]".

== Full Range Mod ==
This will modify the stock RF module for full range. It requires removal of the shield and bypassing of a diode within module. Various methods for doing the bypass exists, so read through the tutorials and decide which you want to try.

== WK-DEVO-S-MOD RF Module ==
If you'd prefer not to fool around with soldering inside the stock RF module, or you damage the stock RF module, you can replace it with Walkera's full range module used in the Devo 6/8/10 transmitters. This requires removal of the stock RF module.

== Add Two 2-way Switches ==
This modification will add two 2-way switches labeled "SW A" and "SW B".

== Add One/Two 3-way Switches ==
This modification will add either one or two 2-way switches labeled "SW A" or "SW A" and "SW B" respectively.

== Arduino to PPMin for Extra Inputs ==
The trainer port can be hijacked for an arduino to provide PPM signals from nearly any combination of switches and potentiometers. This modification effectively takes over the trainer port by mimicking a 2nd connected transmitter and injects PPM signal to the channels. Note that once you do this mod, you will not be able to connect another transmitter to the trainer port.

== LiPo Battery Mod ==
Swap out to a higher capacity LiPo battery. Search around as there are now few manufacturers that make a LiPo specifically for the Devo 7E.
