XS121 Satellite Board

3.3.1

Overview

The XS121 is a 20x20mm satellite board equipped with an A121 pulsed coherent radar sensor that via
FFC (Flat Flexible Cable) can be connected to the Acconeer Evaluation Board XE121. It is not a
mandatory component in the Acconeer A121 Evaluation Kit but can come in handy when you want to
evaluate multi sensor use cases or a use case where space for sensor placement is limited. It is not
possible to operate the XS121 without an XE121 Evaluation board. The XS121 is delivered with an
FFC cable from Molex: 0151660225. The FFC has 20 channels, 0.5mm pitch. The XS121 is
compatible with the Acconeer LH112 lens kit.
