=== 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]] ====

===Routing options===
[[BoraXEVB#SoM.27s_signals_mapping|This table]] helps to map Bora Lite's signals when it is mated with the [[BoraXEVB|BoraXEVB]] carrier board. '''That table assumes that the adapter is populated according to the default mounting option''', which is illustrated in the schematics available [[#Schematics|here]].
At the adapter level, other mounting options are available, however. Please refer to the [[#Schematics|schematics]] for more details.
==== CAN bus ====
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.
