RISC Engine II Product Summary
Page | 7
Introduction
The Blue Chip Technology RE2 (BCT-RE2) sets very high standards for integration of the processor, graphics,
memory, and I/O technologies together with a unique connection system for selected LCDs.
The BCT-RE2 was introduced with two CPU options, 600MHz and 720MHz. The 600MHz CPU was also
available as an extended temperature product. All RE2s are supplied with 256MB of SDRAM and 256MB of
NAND Flash. Further, additional NAND Flash can be added through either the optional μSD Card or optional
MMC socket, if fitted.
From 2015, the BCT-RE2 will have two new CPU options based on a 1GHz CPU, which will be offered as a
Standard temperature or an Industrial temperature board. Although the 600MHz and 720MHz options will no
longer be available, the 1GHz board is able to be clocked down to 600MHz and 800MHz for customers with
applications that may not suit the faster CPU. This can be achieved for Windows CE6 and EC7 via an updated
Graphical Utility
The BCT-RE2 can operate from 7V DC input through to 36V DC input. Power requirements will vary
depending on the LCD panel and other peripherals attached to the RE2.
For example with the older 600MHz BCT-RE2 with the U.R.T. UMSH-8173MD-1T 5.7” Combined LCD and
Touch Screen, the operational power requirements will vary between 5W for Windows CE6, without
applications running, up to 10W with applications running and peripherals attached. With the 1GHz CPU board,
power levels are comparable with the 720Mhz board, indeed running the same application will actually be
slightly lower power level on the 1GHz board, as the CPU will not be working as hard
On its own, the RE2 operates at approximately 2W without power saving.
The BCT-RE2 has the capability to support a Lithium Battery via connector P14 to retain time when the unit is
powered off.

RISC Engine II Precautions
Page | 10
General Precautions
Your Single Board Computer is susceptible to damage by electrostatic discharges. In order to avoid damage,
you should work at an anti-static bench and observe normal anti-static precautions. Wear an anti-static wrist
strap connected to an earth point before opening any packaging.
Where a wrist strap is not available, discharge any static charge you may have built-up by touching an earth
point. Avoid any further movement that could build up another static charge. Touch an earth point from time to
time to avoid further build-up, and remove the items from their anti-static bags only when required
Electro-Static Discharges
If you are going to open up the unit, it is important to realise that the devices on the cards within this unit can be
damaged by static electricity. Bear in mind that the damage caused by static electricity may vary from total
destruction to partial damage, which may not be immediately obvious. This could have an effect on the
product's reliability and warranty. Before opening the chassis, ensure that you take necessary static precautions.
Ideally you should work at an anti-static bench and wear an approved wrist strap or if that is not possible, touch
a suitable ground to discharge any static build up before touching the electronics. This should be repeated if the
handling continues for any length of time.
If it is necessary to remove a board or electronic assembly, place it into an anti-static bag. This will prevent any
static electricity build up damaging the board. Metallised bags are preferred. Do not use black anti-static bags
for any item containing a battery because these tend to be conductive and will discharge the battery.
On-Board Battery
The processor board can be fitted with a Lithium battery. Great care should be taken with this type of battery. If
the battery is mistreated in any way there is a very real possibility of fire, explosion, and personal harm. Under
NO circumstances should it be short-circuited, exposed to temperatures in excess of 100°C or burnt, immersed
in water, recharged or disassembled.
Expired batteries remain hazardous and must be disposed of in a safe manner, according to local regulations.
Le panneau de processeur est équipé d’une batterie de lithium. Le grand soin devrait être pris avec ce type de
batterie. Si la batterie est mistreated il y a de dans de toute façon un possibility très vrai du feu, d’expolosion et
de mal personnel. Dans au cunes circonstances il est sous peu circuité, exposé aux températures au dessus de
100 degrés de centrigrade ou brûlé, immergé dans l’eau, rechargée ou dissassambled.
Les batteries expirées restent dazaedous et doivent être reejetées d’une façon sûre, selon des règlements locaux.
Electromagnetic Compatibility
This product has been assessed operating in representative, standard configurations. As with any PC product,
however, final installation & configuration can vary significantly, and so the following guidelines are offered to
help ensure that compatibility is maintained.
 All components added to a system should either carry appropriate equivalent levels of compliance, or
be tested for compliance as part of the final system, and should be installed in accordance with supplier
recommendations.
 The external enclosure should be securely fastened (with standard lids and covers in place) to ensure
good metal-to-metal contact around the internal electronics

RISC Engine II Precautions
Page | 11
 Any metal back plate must be securely screwed to the chassis of the computer to ensure good metal-to-
metal (i.e. earth) contact.
 Metal, screened, connector bodies should be securely connected to the enclosure.
 The external cabling to boards causes most EMC problems. It is recommended that any external
cabling to the board be totally screened, and that the screen of the cable connects to the metal end
bracket of the board or the enclosure and hence to earth. Round, screened cables with a braided wire
screen are used in preference to those with a foil screen and drain wire. Wherever possible, use metal
connector shells that connect around the full circumference of the cable screen: they are far superior to
those that earth the screen by a simple “pig-tail”.
 The keyboard and mouse will play an important part in the compatibility of the processor card since
they are ports into the board. Similarly, they will affect the compatibility of the complete system. Fully
compatible peripherals must be used otherwise the complete system could be degraded. They may
radiate or behave as if keys/buttons are pressed when subject to interference. Under these
circumstances it may be beneficial to add a ferrite clamp on the leads as close as possible to the
connector. A suitable type is the Chomerics type H8FE-1004-AS.
 USB cables should be high quality screened types.
 Ensure that the screens of any external cables are bonded to a good RF earth at the remote end of the
cable.
Failure to observe these recommendations may invalidate the EMC compliance

P6 – GPIO Connector
The GPIO interface is a flexible, logic-level port providing a mix of dynamically-configured hardware inputs
and outputs. It is designed for use within a chassis with localised electronics. Interfacing to signals which may
pick up noise transients will require buffering and/or conditioning circuits.

The GPIO outputs are designed for flexibility, and will interface to electronics operating with signal levels
between 2.3V & 5.5V DC. The function and direction of the GPIO signals is configured by RE2 software (see
the software manual for details of GPIO port mappings and configuration).
Basic electrical characteristics are as follows:-

Quiescent output current in the high state appears equivalent to a 10K pull-up (short-duration current boosting is
applied, however, during signal transitions to speed up rise/fall times). Optimum performance is achieved with
short cable connections, and minimum capacitive loading on the signal lines.
GPIO VCC
The original release of the RE2 required I/O voltage to be provided to the RE2 at the VCC_GPIO pin
(referenced to 0V_GPIO). In 2012, the Rev 3 release of the SBC allowed for the option to provide VCC from
the RE2 itself.

In order to convert the RE2 to provide GPIO VCC, it is necessary to solder a link across two pads as shown
LK7 is on the underside of the PCB just above the green fuse (F2).
