Thank you for detailed answer.

I have more question if I could.
What does the MCP3208 do and MCP3202+KMZ60? Those only use if I want connect analoge pot's on the board or when I want increase the axis bit resolution?

So ,Where connect the 5 wire of tle 5011 ? That's way this doesn't replace analog pot, if I only change pot's in another original joy?
"5V" ang "gnd" go same place on pro micro but other 3 are individual each from tle 5011 chip?
the tle5011 chip counts that which side (front/back) or orientation has toward the magnet.
The most of pics I saw horizontal assembly but there is verticaly.

Very interesting the "pot'sensor" with this modification could be replace the antenna elevation pot too.
How looks like this PCB?
