Introduction

As known, SBC Lynx is conceived to allow the customer to plug in some additional boards to the mainboard.

This document presents an example of such add-ons. This board provides more interfaces to the SBC, augment expansion pin availability or add the possibility to use a custom board suitable for every needs.

Not all SBC Lynx models support every add-on. We recommend to check the compatibility list.

Extra Ethernet interface (XUAE)

This Addon allows to add an ethernet connector and a 10/100 ethernet interface to SBC Lynx. The interface is seen as an indipendent port and can be easily fully standalone configured.
