Introduction Regulatory Statements This product has been designed and assessed to meet the essential protection requirements of the European EMC Directive (2004/108/EC), the Low Voltage Directive (2006/95/EC), and the R&TTE Directive (1999/5/EC) when installed and used in conjunction with the guidelines provided within this document. [Note that compliance with the R&TTE directive is only required for those versions of the product equipped with radio frequency interfaces].
Firmware Setup Maintenance details We strongly recommend that you study this manual carefully before attempting to interface with the RE3 or change the standard configurations. Whilst all the necessary information is available in this manual we would recommend that unless you are confident, you contact your supplier for guidance.
Product Summary Introduction The Blue Chip Technology RE3 (BCT-RE3) is the next step in the highly successful RE range of all in one compact computers. The BCT-RE3 has multiple CPU options, 1GHz Dual Core and 1GHz Quad Core. Both options are available as extended temperature product.
Electro-Static Discharges It is important to realise that the components on the RE3 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.

Precautions 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.

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 RE3 software (see the software manuals for details of GPIO port mappings and configuration).

Installation P30 – Fan Connector Mating part is Molex 87439-0200 1.5mm PICO-SPOX Pin 1 Vcc_5V Pin 2 Ground/ FanPWM Pin 2 is switched ground with a flyback diode incorporated, to absorb the back EMF from a fan motor. The output can be operated as a digital output (high or low) or as a PWM signal. The fan is driven from the PIC microcontroller, by sending an I2C command from the i.MX6 to the PIC.

Installation Applications The relatively high battery current consumption may be important depending on the application. When using a CR2032 battery, a simple calculation shows that the RTC may be able to hold up for around 34 days without the main power: Based on CR2032 typical capacity of 225mAh 225mAh / 275uA = 818h 818/24 = 34.09 days...
5CFM, this drops to around 12˚C above ambient The IMX6 core temperature is only one factor when designing the RE3 into an enclosure. It is just as important to ensure that the local ambient around the PCB does not exceed the maximum rated for the particular variant.

Firmware Bootloader Firmware Refer to the relevant BCT RE3 Linux/Android User Guide for more details on configuring the RE3 bootloader. The following is a quick summary of how to setup the correct display output. This is achieved via the debug port connected to a control PC running a terminal emulator such as PUTTY.
