I just mount this board with a mixing extruder, 2 Z stepper, switch endstop for X/Y and TOUCH'MI level bed sensor, but it was really hard to find how :

to connect correctly the endstop (in the pinout, you give the endstop signal, but they are 3 pins, which one is one ????)
how to conect correctly the fan, in the pinout, the +/- is not provided
how to connect a servo, 3 pins, no information int the pinout
for standalone drivers 4 jumper ms1 ms2 ms3, but the 4th jumper is for what ???
what is the purpose of bt0 bt1 .. pin ????

I brought one of this board, but i don't will buy other as long as you don't give:

a good pinout or the pcb schematics
the bootloader sources (because i must use marlin as klipper does not work)

Sorry, I ca n’t visit here a few days ago, I will follow the perfect information you said in the near future, thank you very much

Some comments : 1) I don't understand how to connect the "optimal limit switch voltage" 2) I don't understand the purpose of BT0 BT1 (I already asked, but the response don't help me) 3) servo pin number is missing 4) what is UD+ UD- 5) SDA SCL is on the pin on a chipset ?

My two cents

Most endstops are designed for 5V, so a jumper on the left two pins 2 BT0 is for entering in DFU mode, BT1 probably something simular
SERVO0_PIN = PE11 (according to https://github.com/FLYmaker/FLYF407ZG/blob/master/English-firmware/Marlin/src/pins/stm32/pins_FLYF407ZG.h ) 4 UD- UD+ = USB pins for bootloader programing
That seems to be the case

There are more data missing: Outputs: max Amp´s respective RDSon (I fried mine BED FET within just a view seconds ...)

Mounting hole dimensions: I could see in a picture that they are X spaced 144.05mm in but what about Y spacing and Diameter...

yes i know, i use optical endstop. but they is 3 pins on the jumper, so need to indicate how to use them correctly
in the diagram it's better for reading

All holes seem to be same offset from the board edge, so you need to deduct 5.98 form total Y length (the same difference in X). So that would be 105.3mm for center to center in Y.
