ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic component stores, when
handling boards and components.

2.3 Assembly Drawing
For thermal dissipation, a thermal solution enables the PICO52R’s components to dissipate
heat efficiently. All heat generating components are thermally conducted to the heatspreader in
order to avoid hot spots. Images below illustrate how to install the thermal solution on
PICO52R.
1. Standard –Heatsink with fan for PICO52R (see image below):

PICO52R Pico-ITX Board
10 Board and Pin Assignments
2. Optional -- Heatspreader for PICO52R (see image below):
Note
Heatspreader has a large, flat surface on top. It has no fan and no fins. Instead of
cooling by forced air, it is pressed directly up against another large flat surface
(for example: the frame or the inside wall of a sealed container) and heat is
allowed to pass from the small heatspreader out to the larger metal surface.
Heatspreader does not cool the CPU by itself, it only transfer the heat to another
object where it can safely dissipate away from the processor.
The standard heatsink with fan cannot be screwed above heatspreader.

2.4 Jumper and Switch Settings
Jumper is a small component consisting of jumper clip and jumper pins. Install jumper clip on 2
jumper pins to close. And remove jumper clip from 2 jumper pins to open. Below illustration
shows how to set up jumper.
Properly configure jumper and switch settings on the PICO52R to meet your application
purpose. Below you can find a summary table of jumper, switch and onboard default settings.
Note
Once the default jumper or switch setting needs to be changed, please do it under
power-off condition.

The board supports voltage selection for flat panel displays. Use these jumpers to set
LVDS connector (CN4, See section 2.5.3) pin 1~6 VCCM to +3.3V, +5V or +12V. To
prevent hardware damage, before connecting please make sure that the input voltage of
flat panel is correct.
2.4.2 Restore BIOS Optimal Defaults (SW1)
Use SW1 to clear CMOS. Press the tact switch for at least 3 second to restore BIOS
optimal defaults.
2.4.3 Auto Power On (SSW1)
If SSW1 is enabled for power input, the system will be automatically power on without
pressing soft power button. If SSW1 is disabled for power input, it is necessary to
manually press soft power button to power on the system.

2.5.1 Front Panel Connector (CN2)
This is a 2x6-pin header (pitch=2.0mm) for front panel interface.
Internal Buzzer
Pin 1(-) and 2(+) connect the internal buzzer cable, 594H3186800E for buzzer.
Power Status
Pin 4 and pin 3 are for power status button; letting user know the power status of this
board.
Power LED
Pin 6 connects anode (+) of LED and pin 5 connects cathode (-) of LED. The power LED
lights up when the system is powered on.
Power On/Off Button
Pin 8 and 7 connect the power button on front panel to CPU board, which allows users to
turn on or off power supply.
System Reset Switch
Pin 10 and 9 connect the case-mounted reset switch that reboots your computer without
turning off the power switch. It is a better way to reboot your system for a longer life of
system power supply.
HDD Activity LED
This connection is linked to hard drive activity LED on the control panel. LED flashes
when HDD is being accessed. Pin 12 and 11 connect the hard disk drive to the front
panel HDD LED, pin 11 is assigned as cathode(-) and pin 12 is assigned as anode(+).
2.5.2 Inverter Connector (CN3)
This is an 8-pin (pitch=1.25mm) connector which is compliant with Hirose
DF13-8P-1.25V for inverter interface. We strongly recommend you to use the matching
connector, DF13-8S-1.25C, to avoid malfunction.
