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
2.3.1 Installing Heatsink (Optional)
For thermal dissipation, a thermal solution enables the PICO316’s components to
dissipate heat efficiently. All heat generating components are thermally conducted to the
plate in order to avoid hot spots. Images below illustrate how to install heatsink on
PICO316.
Page 16
PICO316 Pico-ITX Board
10 Board and Pin Assignments
2.3.2 Installing Heatspreader (Optional)
The heatspreader acts as a thermal coupling device that all heat generating components
are thermally conducted to the heatspreader in order to avoid hot spots. Heat dissipation
devices such as a heatsink with fan or without fan may need to be connected to the
heatspreader. Images below illustrate how to install the heatspreader on PICO316. And
there is a protective plastic covering on the thermal pads. This must be removed before
the heatspreader can be mounted.

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 PICO316 to meet your application
purpose. Below you can find a summary table of jumpers, switch and onboard default settings.
Note
Once the default jumper or switch setting needs to be changed, please do it under
power-off condition.

2.4.1 LVDS +3.3V/+5V Voltage Selection (JP2)
This is a 2x3-pin (pitch=2.0mm) jumper. The board supports voltage selection for flat
panel displays. Use these jumpers to set LVDS connector (CN6) pin 1~6 VCCM to +3.3V,
or +5V. 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 (JP2)
This is a 2x3-pin (pitch=2.0mm) jumper. Put jumper clip to pin 2-4 for a few seconds then
move it back to pin 4-6. Doing this procedure can restore BIOS optimal defaults.
2.4.3 Auto Power On (SW1)
If SW1 is enabled for power input, the system will be automatically power on without
pressing soft power button. If SW1 is disabled for power input, it is necessary to
manually press soft power button to power on the system.

Hardware Description 23
Chapter 3
Hardware Description
3.1 Microprocessors
The PICO316 supports Intel® Pentium® N4200 and Celeron® N3350 processors which enable
your system to operate under Windows® 10 environments. The system performance depends
on the microprocessor. Make sure all correct settings are arranged for your installed
microprocessor to prevent the CPU from damages.
3.2 BIOS
The PICO316 uses AMI Plug and Play BIOS with a single 64Mbit SPI Flash.
3.3 System Memory
The PICO316 supports one 204-pin DDR3L SO-DIMM socket for maximum memory capacity
up to 8GB DDR3L SDRAMs. The memory module comes in sizes of 2GB, 4GB and 8GB.

Chapter 4
AMI BIOS Setup Utility
The AMI UEFI BIOS provides users with a built-in setup program to modify basic system
configuration. All configured parameters are stored in a flash chip to save the setup information
whenever the power is turned off. This chapter provides users with detailed description about
how to set up basic system configuration through the AMI BIOS setup utility.
4.1 Starting
To enter the setup screens, follow the steps below:
1. Turn on the computer and press the <Del> key immediately.
2. After you press the <Del> key, the main BIOS setup menu displays. You can access the
other setup screens from the main BIOS setup menu, such as the Advanced and Chipset
menus.
Note
If your computer cannot boot after making and saving system changes with BIOS
setup, you can restore BIOS optimal defaults by setting JP2 (see section 2.4.2).
It is strongly recommended that you should avoid changing the chipset’s defaults. Both AMI
and your system manufacturer have carefully set up these defaults that provide the best
performance and reliability.
4.2 Navigation Keys
The BIOS setup/utility uses a key-based navigation system called hot keys. Most of the BIOS
setup utility hot keys can be used at any time during the setup navigation process. These keys
include <F1>, <F2>, <Enter>, <ESC>, <Arrow> keys, and so on.
Note
Some of the navigation keys differ from one screen to another.

The BIOS Flash utility is a new helpful function in BIOS setup program. With this function you
can easily update system BIOS without having to enter operating system. In this appendix you
may learn how to do it in just a few steps. Please read and follow the instructions below
carefully.
1. In your USB flash drive, create a new folder and name it “Axiomtek”, see figure below.
2. Copy BIOS ROM file (e.g. PICO316.005) to “Axiomtek” folder.
3. Insert the USB flash drive to your system.
4. Enter BIOS setup menu and go to Advanced\Utility Configuration. Select BIOS Flash
Utility and press <Enter>.

5. BIOS automatically detect all USB drive(s) attached to the system. In this example only
one USB drive is attached to the system. That’s why, you can see only one device is
displayed in figure below.
6. Select the USB drive containing BIOS ROM file you want to update using the <> or
<> key. Then press <Enter> to get into “Axiomtek” folder.
7. Now you can see the BIOS ROM file on the screen, press <Enter> to select.
