### Voltage sense
|
|
### The labels and equations reverse-engineered by measuring voltages on the board, finding
|
|
### voltage dividers and comparing the voltages to what is reported in the BIOS.
|
|
###
|
|
### No datasheet for IT8732F has been discovered so its unknown what the recommended wiring is.
|
|
### VIN[0-7] pinout has been taken from IT8782F datasheet it seems to match.
|
|
|
|
# These go straight to the IT8732F, confirmed in BIOS Setup
|
|
label in0 "Vcore"
|
|
label in1 "DDR 1.5V"
|
|
|
|
# These looks to be a second 3.3V input with a 10k/20k divider
|
|
label in2 "+3.3V_2"
|
|
compute in2 @*((10/20)+1), @/((10/20)+1)
|
|
|
|
# in3 is labeled as +3.3V by the it87 driver, supposedly wired internally inside the chip
|
|
# The reported value is halved
|
|
compute in3 @*2, @/2
|
|
|
|
# Resistors could not be reverse engineered from the board, a simple scaling factor was calculated
|
|
label in4 "+12V"
|
|
compute in4 @*6.59, @/6.59
|
|
|
|
# in5 and in6 are unknown, one of them is most likely the +5V rail but the +5V divider voltage
|
|
# and the measured voltages do not match.
|
|
# Specifically, the +5V divider outputs 1.86V but in5 reads 1.44V and in6 reads 2.78V
|
|
|
|
# in7 is labeled as 3VSB by the it87 driver
|
|
# The reported value is halved
|
|
compute in7 @*2, @/2
|
|
|
|
# in8 is labeled as Vbat by the it87 driver, probably wired internally inside the chip
|
|
# The reported value looks to be nonsense as it reports 1.6V without a battery inserted.
|
|
# Ignore for now
|
|
ignore in8

### Temperatures
|
|
### The BIOS reports only one temperature sensors and labels it "System temperature3", it's obviously temp3
|
|
### Other temp inputs are not wired
|
|
ignore temp1
|
|
ignore temp2
|
|

|
###
|
|
### System contains only chassis fans, confirmed in BIOS
|
|
### The RPM reported for PWM value of 128 is around 5500 RPM
|
|

|
|
label fan2 "Chassis fan 2"
|
|
label fan3 "Chassis fan 3"
