Federal Communications Commission Statement
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio energy. If this equipment is not installed and used in accordance with the
manufacturer’s instructions, it may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to correct the interference by one or more
of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment to an outlet on a circuit different from that to which the receiver is
connected.

Consult the dealer or an experienced radio/TV technician for help.
This board is designed for installation in a shielded enclosure (metal or plastic with conductive
coating). Shielded cables are required on LAN and serial ports to assure compliance with FCC
regulations.
A copy of the test report will be provided on request.
Note: apu has been tested as a CPU board, installed in an enclosure, with the top cover removed.
No further testing should be required if the board is used with other FCC tested modular
components. Please see http://www.fcc.gov/oet/ for more details. The responsible party for FCC is
the importer.
Recycling / disposal
Do not discard electronic products in household trash!
All waste electronics equipment should be recycled according to local regulations.
Information for the recycler:
Please cut off Lithium battery, if present, for separate recycling.
PC Engines enclosures are made of aluminium.

Introduction / Features
PC Engines apu boards are small form factor system boards optimized for wireless routing and
network security applications.
CPU
AMD G series T40N or T40E APU, 1 GHz dual core (Bobcat core) with 64 bit
support, 32K data + 32K instruction + 512KB L2 cache per core
DRAM
2 or 4 GB DDR3-1066 DRAM
Storage
Boot from SD card (built-in adapter, connected through USB), USB or m-SATA
SSD. 1 SATA data + power connector.
Power
12V DC, 2.5 mm center pin, center positive. About 6 to 12W depending on CPU
load. Recommend 12V adapter rated for at least 1.5A to provide margin for
peripherals.
Expansion
2 miniPCI express (one with SIM socket for 3G modem), LPC bus, GPIO header,
I2C bus, COM2 (3.3V RXD/TXD).
Connectivity
3 Gigabit Ethernet (Realtek RTL8111E), 1 DB9 serial port (console).
Firmware
CoreBoot open source system BIOS with support for iPXE and USB boot.
Form factor
6"x6" (152.4 x 152.4 mm), fits in our case1d2*u enclosures.
Cooling
Conductive cooling from the CPU and south bridge to the enclosure.
Heat spreader assembly
The apu CPU and south bridge are passively cooled by heat conduction to the enclosure.
The apu board should not be powered up without cooling except for brief bench tests.
The included heat spreaders are designed for our enclosures. Third party enclosures should work if
they are made from aluminium, and have a board standoff height of 5 mm. If in doubt, please
contact us. Based on our measurements, at full load the CPU runs a few degrees cooler in the black
(case1d2blku) or red (case1d2redu) enclosures, compared to the plain anodized enclosure
(case1d2u).
Photos for this assembly procedure can be found at www.pcengines.ch/apucool.htm .

Remove DB9 hex nuts. Using a small x-acto knife or similar, peel transparent backing foil from
the small heat spreaders. Apply to CPU and south bridge. Then peel the blue cover foil from the
heat spreaders.

Place the alu heat spreader (blank side down) over CPU and south bridge. Make sure to avoid
conflict with nearby through hole components. Peel the cover foil.

"Bottoms up" - hold the enclosure base upside down, feed the board DB9 and LAN connectors
through the openings. Lightly press board and enclosure base together to stick the heat spreader
in place.

Turn around and carefully press down around CPU and heat sink to get good contact between
enclosure and heat spreader. Then insert screws and hex nuts.
Please do not disassemble the unit needlessly, the thermal conductive pads are easily damaged.
Replacement pads are available from us on request.

Getting started…
-
Please install heat spreader as described in the prior section.
-
Insert a boot device (SD card, mSATA SSD, USB stick, or PXE through LAN).
-
Connect serial port to a PC through null modem cable (RXD / TXD crossed over). Set terminal
emulator to 115200 8N1.
-
Connect Ethernet as needed.
-
Connect a 12V DC power supply to the DC jack. Power supply should be able to supply at least
18W for some margin. To avoid arcing, please plug in the DC jack first, then plug the adapter
into mains.
The board should now power on. All three LEDs will light during BIOS POST, then the system will
try to boot. You should see BIOS messages on the serial console. Press F12 for boot device
selection:

Operating system compatibility
Please keep in mind that apu boards do not include a keyboard controller. Some boot loaders may
hang and need to be modified.
FreeBSD
Please do a BIOS upgrade to build date April 1 2014 or later.
FreeDOS
Tested ok, booting from SD card or USB stick.
FreeDOS serial console is broken as usual, backspace does not behave the way it should, use ^H
instead.
CoreBoot is limited to two active USB storage devices, and does not react to kindly to hot plug
events.
Linux
Please contact support@pcengines.ch for support if necessary. We provide sample images for
tinyCore Linux. To access the thermal sensor under Voyage Linux:
# apt-get install lm-sensors
# sensors-detect
…
AMD Family 12h and 14h thermal sensors...
(driver `k10temp')
…
# sensors
k10temp-pci-00c3
Adapter: PCI adapter
temp1:
+57.4 C (high = +70.0 C)
(crit = +100.0 C, hyst = +97.0 C)
Success!
NetBSD
NetBSD 6.x works.
OpenBSD
Please do a BIOS upgrade to build date April 1 2014 or later.
pfSense
