Introduction

This is a user guide about the JetCis_130 which is a platform to evaluate the Mira130 sensor. The kit
is built on top of an NVIDIA Jetson developer kit. The purpose of this guide is not to explain the sensor
functionality, nor will it replace the NVIDIA Jetson manual. For that purpose, please refer to the
appropriate datasheet/manual. The goal of this document is to get started quickly with this evaluation

kit, to connect the camera board to the NVIDIA Jetson, to explain the GUI and how to take pictures
with the kit. The EVK does not need an external computer to be operated, instead the NVIDIA Jetson
runs GNU/Linux Ubuntu.
