2.16. Power switch
SW1 is a slide switch to control the power of the MIMXRT1064 EVK Board when the power supply is
from J2. The function of this switch is listed below:
•
Sliding the switch to the ON position connects the 5V power supply to the Evaluation board
main power system.
•
Sliding the switch to OFF position immediately removes all power from the board.
2.17. ON/OFF button
SW2 is the ON/OFF button for MIMXRT1064 EVK Board. A short pressing in OFF mode causes the
internal power management state machine to change state to ON. In ON mode, a short pressing
generates an interrupt (intended to be a software-controllable(power-down). An approximate 5 seconds
or more pressing causes a forced OFF. Both boot mode inputs can be disconnected.
2.18. Reset button
There are two Reset Button on the EVK Board. SW3 is the Power On Reset Button. Pressing the SW3 in
the Power On state will force to reset the system power except SNVS domain. The Processor will be
immediately turn off and reinitiate a boot cycle from the Processor Power Off state. SW4 is Reset
Button.
2.19. USER button
SW8 is the USER Button(GPIO5-00) for developers using. Pressing can produce changes in high and
low levels.
2.20. Sensor
U32 on the EVK Board is a 6-Axis Ecompass (3-Axis Mag, 3-Axis Accel) sensor FXOS8700CQ. The
Ecompass is connected to i.MX RT1064 I2C1 port.
NOTE
The sensor on some boards are unpopulated.
2.21. User interface LED indicator
There are four LED status indicators located on the EVK Board. The functions of these LEDs include:
•
Main Power Supply (D3)
Green: DC 5 V main supply is normal.
Red: J2 input voltage is over 5.6 V.
Off: the board is not powered.
