Hello all.
Is it possible to install the rf module from an old Walkera WK-2801-pro to Devo 7e?
I am interested to run Devo 7e under dsmx protocol with telemetry and full range power.

I am planning to remove the stock module and install the WK-2801 module alone. It's a CYRF6936 module. Should the pinout remain the same as you suggested?
Thanks for your time.

Use Wiki to install your module to Devo7e.

If one module is being installed, CSN should connect to the 'TMS' pin.

After a year I finally got the time and install the RF module from my old WK-2801 pro, to Devo 7E.
I follow the pinout suggested by vlad_vy and it works fine.

Also now I can bind Devo 7E, with Spektrum SPM4650 (SRXL2 protocol) micro receiver. With the stock RF module I couldn't do it.
With 150mW output on TX, the range goes up to 520m before rxloss and GPS rescue begin (2.5" quad with Betaflight 4.4.2.).

So I guess now I am jumping to expressLRS pages for more range?
