Overview

Summary

In general, the process for selecting image sensors and interposers are use case specific, but there are some common use cases that the VOXL ecosystem supports out of the box.

The following describe two configurations that are available as development kits.

Lower on this page, general information about the interposers and image sensors will be listed that provide customization options.

Please, Don’t Hot Swap!

When playing with the hardware, please ensure you unplug VOXL 2 Mini from the power supply and USB when changing image sensors. If you have the system powered on, you can damage things!

Stereo Flex not Currently Supported

The stereo sensor flex is not currently supported in the VOXL 2 Mini camera configurations.

Hardware Information

Camera Configuration Summary

There are four 4-lane CSI and four CCI interfaces exposed on two connectors, J6 and J7.

  • J6 - CCI0/CSI0 and CCI1/CSI1, representing HW IDs 0/1 respectively
  • J7 - CCI2/CSI2 and CCI3/CSI3, representing HW IDs 2/3 respectively

m0104-image-sensors-config

Custom flexes can be made to interface to J6/J7, or the following interposers can be used.

Interposers

The VOXL 2 Mini (board ID M0104) ecosystem consists of “interposers” to provide image sensor connections to the board.

These interposers route the image sensor contral and data, and also interfaces like SPI/UART/I2C/GPIO in some cases. The focus of this document is just image sensor connections.
