UDOO Bricks connector
This connector, managed by the Intel
®
Curie microcontroller, allows augmenting features offered by the
UDOO x86 board, by adding the UDOO Bricks external sensor modules.
The connector used is type MOLEX p/n 53398-0571 or equivalent, with the pinout shown in the table
on the left.
Mating connector: MOLEX 51021-0500 receptacle with MOLEX 50079-8000 female crimp terminals.

SPI Header
This pin header, managed by the Intel
®
Curie microcontroller, has been implemented in order to
allow the compatibility with existing Arduino sketches.
The connector, CN16 is an internal 10-pin standard right angle male pin header, p 2.54 mm, h= 6.1mm.
SPI_MISO: SPI Master In Slave Out input signal, electrical level +5V_C. It is managed through the Intel
®
Curie
SPI master port #1
SPI_MOSI: SPI Master Out Slave In output signal, electrical level +5V_C. It is managed through the Intel
®
Curie SPI master port #1
SPI_CLK: SPI Clock output signal electrical level +5V_C. It is managed through the Intel
®
Curie SPI master port #1
RESET: Sketch reset input signal, electrical 5V_C

ARDUINO int expansion connectors
On four dedicated female headers p.2.54mm are realised both the Arduino 101 interface (managed by the Intel
®
Curie microcontroller) and the expansion
interface, managed by the Intel
®
Braswell SoCs.
On the
“
internal
”
rows of these headers is implemented the Arduino interface, while on the
“
external
”
rows are available the expansion interfaces.
This will allow the plugging of Arduino 101-compatible sketches on these connectors, while leaving the further expansion interfaces free for use.
