[[File:Axelevb-lite-01.png|500px|frameless|border]]==Introduction==AxelEVB-Lite is a carrier board designed to host [[Axel Ultra SOM:Category:AxelUltra|AXEL ULTRA]] and [[:Category:AxelLite|Axel system-on-moduleAXEL LITE]](through an adapter) SoMs. It exports some specific peripherals connectors and acts as an adaptation board used in combination with [[:Category:Dacu|Dacu]] carrier board.
==Block Diagram==
The following picture shows Axel-EVB-Lite's block diagram:
* Pin strip expansion connectorsfor additional peripherals* 2x 140 pin connectors for [[Dacu]] carrier board.* Support for the following SOMs:** Axel Ultra ** Axel Lite (through the [[AxelEVB-Lite-Adapter_(AxelLite) | Axel Lite Adapter]])

| <strike>ETH0 interface</strike>
| <strike>Mistake in the connection of the center tap pins.
