As I already suggetsed in this post: https://www.rcgroups.com/forums/show...&postcount=754 I would like to start a List of hardware that is known to work with openTX and similar firmwares.
As a start this is the list of components I used to do my Futaba FX-18 to Open FX-18 conversion:

I did a very simple conversion using a HK T6 transmitter and a Turnigy 9XR main pcb.
The 9XR connector pinouts are in a pdf file here.
There is no display, it is running er9x firmware, and holds one model that is loaded or modified with eepe.

MCU adapter board:

(if the link doesn't work, just search for 'TQFP 64 pcb' on ebay).
I prefer the rectangular ones, because they are a bit smaller than the square ones.
Plus they have plenty extra holes for crystal, capacitors, and some spare VCC and GND connectors.

LCD ZIF adapter board:

(or search for '0.5 mm pitch adapter board' on ebay)

Hi plane_spotter,

In the picture on Ebay it looks as if pin 25 on the 0.5mm pitch adapter board is not connected to anything...
Is that correct ? Didn't that cause problems with your LCD?

No! Keep going! That was exactly the intention of this thread.
