Power Control
Power Supply
The SMARC-sAMX6i supports a power input from 3.0-5,25V. The supply voltage is applied through the VCC pins (VCC) of the
module connector.
Power Button (PWR_BTN#)
The power button (Pin P128) is available through the module connector described in the pinout list. To start the module
via Power Button the PWRBTN# signal must be at least 50ms (50ms ≤ t < 4s, typical 400ms) at low level (Power Button
Event).
Pressing the power button for at least 4seconds will turn off power to the module (Power Button Override).
CB_POWER_BAD#
The SMARC-sAMX6i provides an external input for a Carrier Board Power Bad signal (Pin S150). The implementation of this
subsystem complies with the SMARC Specification. CB_POWER_BAD# is internally pulled up to 3.3V and must be high level
to power on the module.
Reset Button (RST_CB_IN#)
The reset button (Pin P127) is available through the module connector described in the pinout list. The module will stay in
reset as long as RST_CB_IN# is grounded.

This might not be the maximum load a module can have, but due to the lack of standardized stress test software for ARM
processors this data cannot be provided.
