5.12 Kontron Feature connector
The Kontron Feature connector provides additional interfaces such as I2C, SMBus or Power Control Signals. See the
table below for detailed pin-out description
Pin Signal Level Signal Description
1 PWR_+5V 5V power +5V UL-protected with inductor (600R@100MHz, 1A)
2 GPO2 3.3V-O General-purpose power management event output
3 #BATLOW 3.3V-I
Battery low input. May be driven low by external circuitry to signal that the system
battery is low, or may be used to signal some other external power management
event.
4 GPI2 3.3V-I General-purpose power management event input
