SV08 64bit controller pin-out

Sovol SV08
1

I’ve been trying to find what each connector on the controller does and the pin mapping as in FAN2 = PA3 stuff. Has anyone at Sovol released this information?

It’s in the SV08 repo in github:

SV08/Motherboard/MCU_PIN_definition.pdf at main · Sovol3d/SV08 (github.com)

I found three PDF files but none of them show the actual mapping as in:
J1.1=+5
J1.2=PA1
J1.3=GND

If you look at the way BTT maps their controller boards along side of each connector it shows which pin is what, easy to follow., hard to screw up.

I just want to know the mapping for the XYZ stop pins and what voltage they are using on any connector (+5 or +24), I can always break out my Fluke voltmeter but it would be nice if they provided a detailed pin map.

I just added a USB A to USB C cable to the USBX2 where the camera is plugged into(after I removed the heat glue gunk), I need another MCU added to control a chamber heater and a CPAP exhaust fan, another new cable routed to replace the filament sensor cable with 4 wires instead of three allowing me to use the BTT SFS V2.0 since Klipper now supports filament pulse detection. .

Does not show which pin is which value of all ports

e.g. Filament Detraction PE9; Danger to assume, Blue smoke, could maybe try a multi meter but tat is a big job just to find which pin is +5v which one is the signal and which is ground

The other problem with using an Voltmeter is pull-up resistors, with a pull-up resistor a pin shows what ever voltage that is applied to the pull-up…

It is now 12/5/2024, 5 months since my request for pin information:

P2:FAN3 shows K_FAN3:PB0 K_FAN2_FG:PB3

The connector on the left side below the extruder connector in Sovols image shows as
P1:FAN4 K_FAN3:PB0 K_FAN2_FG:PB3 on the PCB it says P1:FAN4 - If this was the same signals as P2 then plugging the fan into P1 instead of P2 the fan should still turn on, it does not.
After 5 months “SOVOL” has yet to OPEN SOURCE the information or to put it another way, you have miss-labeled the P4 connector and refuse to correct it. I ask earlier to be put on the list to purchase the new SV08 MINI, Please remove my name, I’ll go shopping for a manufacture that responses to failures by fixing things without the customers having to beg for months. NOTE: P1:FAN4 is where the factory has the front cover fan plugged into, remove the front cover, unplug P1.
The issue is what CPU pins does P2 FAN3 use?

in printer.cfg this is defined, maybe that helps ? :

pin: extra_mcu:PA7
max_power: 1.0

[fan_generic fan1] # front model cooling fan
pin: extra_mcu:PB1
max_power: 1.0

[fan_generic fan3] # exhaust fan
pin: PA2
max_power: 1.0

[heater_fan hotend_fan]      
pin: extra_mcu:PA6   
max_power: 1.0
