* routes the signals from the AxelLite pins to the AxelEVB-Lite mating connectors
{{ImportantMessage|text=This page provides information for the AxelEVB-Lite Adapter board model S-XLADP0000I1R (BOM 2.0.0), provided with XELK kits version 2.1.0 and above. If you have a board from a previous version of the XELK kit (older than 2.1.0), please contact [mailto:support-axel@dave.eu support-axel@dave.eu].}}
== Block diagram ==The following images show the top and bottom views of the AxelEVB-Lite-Adapter:
J1, J2 and J3 are Hirose FX8C-140S-SV connectors that match the [[AxelEVB-Lite#Connectors_pinout | AxelEVB-Lite SOM connectors' pinout]].
=== J4 - JTAG ===
=== J5 J4 is a SAMTEC FSI- MicroSD ===110-03-G-S connector. The following table reports the connector's pinout:
