Introduction

Axel-evb-lite-revA 02.jpg

AxelEVB-Lite is a carrier board designed to host AXEL ULTRA and AXEL LITE (through an adapter) SoMs. It exports some specific peripherals connectors and acts as an adaptation board used in combination with Dacu carrier board.


200px-Emblem-important.svg.png This page provides information for the AxelEVB-Lite carrier board model S-EVBA1000C1R (BOM 1.0.4), provided with XELK kits version 2.1.0 and above. 200px-Emblem-important.svg.png

XELK 2.0.0 documentation

If you have a board from a previous version of the XELK kit (older than 2.1.0) please follow this page: http://wiki.dave.eu/index.php?title=AxelEVB-Lite&oldid=2970

Issue Description
ETH0 interface Mistake in the connection of the center tap pins. They should be separated from one another and connected through separate 0.1μF common-mode capacitors to ground (for further details (eg: connection and selection of the magnetics), please refer to the Micrel KSZ9031RNX datasheet).
