Using the classic breadboard creates a lot of confusion and fake contacts
because there are many wires to connect

I will try to make schematic if you want make your own LM317 power supply |
SPI interface have high speed refresh but uses many pin (little sacrifice for performance)
You can use also SSD1306 0.96" 128x64 4 wire SPI interface
1.3" OLED SH1106 128x64 | 4 wire SPI interface |

You can reuse the original gimbals of transmitter |
You can use a new gimbals without mechaninal Sub Trim
Software will provide basic electronic Sub Trim adjustment

Unfortunately you have to sacrifice but can be reused for final cabling |
If you need you can add optional switch for CH5 / CH6 and slide switch for V-MIX function

For testing you can use any type of push button
If you want a good functionality is necessary to solder buttons on prototype PCB
and remember to solder 100nF capacitors for every input pin and wires on PCB buttons
"Otherwise you definitely have trouble with the menu"

Long Push button switch is needed for for the final assembly
It must come out of the transmitter housing
2S (7.4V) battery pack is enough for a few hours
Lithium 2S with balance cable seems to be preferable
