== Introduction ==
* routes the signals from the AxelLite pins to the AxelEVB-Lite mating connectors
{{ImportantMessage|text=There are two versions of the adapter. Revision 0 is used in combination with the [[AxelEVB-Lite_rev.0|AxelEVB-Lite revision 0]]. Revision A is used in combination with the [[AxelEVB-Lite|AxelEVB-Lite revision A]].}} ===Revision 0===The following images show the top and bottom views of the AxelEVB-Lite-Adapterrevision 0:

=== J5 - MicroSD =Boot mode selection == The signals of the SD1 interface are routed following sections detail how to select the J5 microSD memory card connector. The following table reports boot option depending on the connectoradapter's pinout:revision.
For further details, please refer to [[Boot_options_(AxelLite) | this page]], which describes the available boot modes thoroughly.===Revision 0===This adapter provides a switch that allows selecting the boot device according to the following table. The available boot options differ depending on the Axel Lite type. In this regard, there are basically two types: those that are equipped with both NOR and NAND flash, and those that are equipped with NAND flash only.{| class="wikitable" |+! rowspan="2" |Axel Lite type! colspan="2" |S1.2position

It is worth remembering that, when using Axel Lite in combination with AxelEVB-Lite revision 0, the S5, S6, S7, S8, and S9 switches of the carrier board don't affect the boot options.
===Revision A===
Revision A does not integrate any switch. To select the boot source, please use the S9.2 switch provided by the [[AxelEVB-Lite#Boot_configurations|AxelEVB-Lite rev. A]] board instead.
