Sensor interrupt
The RB5 implements a SSC interrupt for sensor interrupts that is the 1.8V voltage rail. The
signals are:
ACCEL_INT: Connects to GPIO_112 of QRB5165 SoC, Be configured to Accelerometer
INT.
GYRO_INT: Connects to GPIO_113 of QRB5165 SoC, Be configured to Gyroscope INT.
MAG_DRDY_INT: Connects to GPIO_123 of QRB5165 SoC, Be configured to
Magnetometer data INT.
MAG_INT: Connects to GPIO_122 of QRB5165 SoC, Be configured to Magnetometer
INT.
PS_INT: Connects to GPIO_129 of QRB5165 SoC, Be configured to Proximity INT.

Other signals on Tertiary Low Speed Connector
The RB5 board implements more source voltage at the Lowe Speed Expansion Connector.
The signals are:
VREG_L5C_1P8: Connects to L5 LDO of PM8250 PMIC, Can be as sensor IO voltage
source.
VREG_L8C_1P8: Connects to L8 LDO of PM8250 PMIC, Can be as sensor IO voltage
source.
VDC_5V: Connects to a board DC buck power 5V, Can be as a 5V voltage source.
VBAT: Connects to a board DC buck power 4.2V, Can be as a 4.2V voltage source.
