<section begin=Body/>=~~Introduction~~=Connectors and Pinout Table==

This chapter contains the pinout description of the BORA Xpress module, grouped in six tables (two – odd and even pins – for each connector) that report the pin mapping of the three 140-pin BORA Xpress connectors.

=== Connectors description ===

In the following table are described the interface connectors on [[:Category:Bora | Bora]] SOM:

{| class="wikitable"

|-

!Connector name

!Connector Type

!Notes

!Carrier board counterpart

|-

|J1, J2, J3

|Hirose FX8C-140S-SV<br>3x140 pins 0.6mm pitch connectors

|

|Hirose FX8C-140P-SV''<x>''

where ''<x''> stays for:

* ''empty'' = 5 mm board-to-board height

* 1 = 6 mm board-to-board height

* 2 = 7 mm board-to-board height

* 4 = 9 mm board-to-board height

* 6 = 11 mm board-to-board height

|}

The dedicated carrier board must mount the mating connector and connect the desired peripheral interfaces according to BORA pinout specifications. See the images below for reference:

===Pinout table naming conventions ===

Each row in the pinout tables contains the following information:
