Applies to SBC Lynx

Applies to ADD-ON SBC-LYNX

Introduction[edit | edit source]

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 avalable add-on. We recommend to check the compatibility list.

Additional industrial I/Os (XUAL)[edit | edit source]

This add-on examples how to add an isolated relay, digital isolated I/Os and an ADC interfaces to the SBC Lynx.

The Add-on fits on J53 and J54 connectors, but uses signals and powers from J54 connector only.
