Breakout board for camera module e-con AR1820HS and Auvidea J100 + Jetson TX1

Introduction

I have got to the point where the integration of USB3.0 cameras into the Chihuahua-VR platform (see also VR tags) is not a good idea. The main downsides are:

  • extra board and chipset with protocol switching
  • lower bitrate via USB and higher CPU usage for data handling
  • problem with Jetson TX ISP integration
  • frames syncing for stitching

Alternatively, we can use the MIPI/CSI interface which has many upsides:

  • very high bitrate
  • simpler interface
  • very good Jetson TX1 support
  • easy integration with ISP
  • better memory management of MIPI data
  • and many more…

Abstract overview

Basically we have to wire properly the board connectors and provide the power on the required levels.

Breakout board overview

There are 2 connectors on the camera module side and 1 final connecter between our breakout board and Auvidea J100. The camera modules requires 4 levels of voltage and correct power up sequence.

Delivery and testing

I have already ordered all parts and waiting to do the final test. I will post the follow up informations.
