Push the module down flat and place the heatsink spacer on the module with the smooth side facing up. Make sure the orien-
tation is correct by checking alignment of the mounting holes. Place the heatsink on the spacer and screw it down gently using
the four included M2.5 screws.

2.4 Mount the Fan (optional)
The fan is only necessary in exceptionally high ambient temperatures. Under normal conditions, the RK3399-Q7 operates
passively cooled.
Place the fan on the heatsink and clip it into place using the provided holder. Connect the cable to the header labeled FAN on
the baseboard.
2.5 Power Up
The EVK modules comes preloaded with software that boots into a full desktop environment on the HDMI output. For boot-
loader configuration and Linux console the serial interface can be used. Connect either a Micro-USB or RS-232 cable to the
corresponding port. Select the correct UART with UART selector slider (1). For Micro-USB the slider has to be in the right
position to route the default console UART0 to the USB UART bridge. For RS-232 the slider has to be in the left position and
the protocol slider (2) has to be in the RS-232 position.
Connect the power supply and verify the sliders are in the position Normal Boot (4) and Normally Off (5). Press the Power
Button (6) to power the board. You will see the boot progress and later on a login prompt on the serial interface. If a HDMI
display is connected video output will follow shortly after.
