== Introduction ==

BORA Lite requires a dedicated adapter to be plugged to the [[BoraXEVB | BoraXEVB carrier board]]. This adapter:

* provides the SODIMM socket for the BORA Lite SOM
* provides the following additional features:
** microSD slot (for SD boot)
** JTAG connector
** CAN traslator for testing the CAN bus on BoraXEVB
* routes the signals from the BORA Lite pins to the BoraXEVB mating connectors

The following images show the top and bottom views of the BoraLite Adapter:

== Connectors' pinout ==

=== J1 - SODIMM connector ===

J1 is a TE Connectivity 204-pin SODIMM socket. The pinout matches the [[Pinout_(AxelLite) | Axel Lite pinout]].

=== J4, J5, J6 - BoraXEVB mating connectors ===

J4, J5 and J6 are Hirose FX8C-140S-SV connectors that match the [[BoraXEVB#Connectors_pinout | BoraXEVB SOM connectors' pinout]].

=== J2 - [[On_board_JTAG_connector_(BoraLite)|JTAG]] ===

J2 is a SAMTEC FSI-110-03-G-S connector. The following table reports the connector's pinout:

== CAN ==
Pins IO_L6P_T0_34 and IO_L19P_T3_34 can be used as CAN_TX and CAN_RX for the CAN0 interface. The BoraLite adapter provide the [http://www.ti.com/lit/ds/symlink/sn65hvd230.pdf SN65HVD232] CAN bus transceiver required for proper CAN bus bus interface.

The CAN_L and CAN_H translated signals are routed to the J5.103 and J5.105 connector pins on BoraXEVB.
