The OAK-D-IoT-75 baseboard has three on-board cameras which implement stereo and RGB vision, piped directly into the DepthAI SoM for depth and AI processing. The data can be then output to a host via USB 3.1 Gen1 (Type-C) or via ESP32 WiFi interface. If you are new to OAK IOT devices, you can check Getting started with OAK IOT devices tutorial.

Minimal and maximal perceiving distances of the camera

Minimal depth perceiving distance of the camera depends on mono camera FOV, resolution, baseline and stereo depth mode, more info is available on the Stereo Depth documentation.

OAK-D-IOT-75 has a baseline of 7.5cm and by varying the resolution and stereo depth mode, we get the following minimal depth perceiving distances:

  • Min distance (800P): ~ 70cm

  • Min distance (400P): ~ 35cm

  • Min distance with extended disparity (800P): ~ 35cm

  • Min distance with extended disparity (400P): ~ 19.6cm

Maximal perceiving distance for OAK-D-IOT-75: 38.4 meters

For more information about the maximum distance see the Stereo Depth documentation.

Getting started

OAK-D-IoT-75 Integrates ESP32-WROOM-32D (Wi-Fi 2.4 GHz to 2.5 GHz) and in terms of power consumption the device accepts 5V (+/-10%) from a 5.5m x 2.5mm barrel jack or via USB 3.1 Gen1 Type-C

Interfacing with the DepthAI SoM is also possible with DM1098OBC_WiFi connector pads J5, and J6. These pads are designed for the Molex/53047-0810 or equivalent. Please refer to the schematics for pinout information.

The reset button resets the OAK-SoM only.

The 5V LED indicates 5V power is present on the DM1098OBC. The PG LED indicates “power good” from the OAK-SoM. The “RUN” LED indicates that the DepthAI SoM is not in reset.

Here is an example how to connect to the wifi and creates a basic http file server.
