SMARC-sXBTi / Product Specification

3.5 Power Control

Power Supply

The SMARC-sXBTi supports a power input from 3,0V - 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-sXBTi provides an external input for a Carrier Board Power Bad signal (Pin S150). The implementation of this

subsystem complies with the COM Express® 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.
