OAK IoT series is now community-supported only and is provided as-is. This means we won’t update it and don’t provide support for it.

The OAK-D-IoT-40 (16 MB NOR Flash) is the Embedded/IoT design of OAK-D. It can be used completely standalone, or via USB with a host like normal USB-only variants of DepthAI.  It has a built-in ESP32 which provides WiFi, Bluetooth (including BLE), as well as other interfaces.  

And like the OAK-D, this model includes the BNO085 IMU which is supported in the DepthAI API

This embedded variant includes a 16MB NOR flash, and boot-switch capabilities such that it can be booted over USB, or set to boot out of NOR-flash, for communication with the onboard ESP32 over SPI.

We also sell a variant with 128MB NOR Flash.

Where do I find the SPI APIs and reference code?

• depthai-spi-api - API of the SPI protocol
• depthai-spi-library -   DepthAI SPI Library
• esp32-spi-message-demo - ESP32 reference app for interfacing with DepthAI over SPI

About the OAK-SOM-IoT in this OAK-D model

This OAK-SOM-IoT system on module is what powers this OAK-D model.  This modular design allows you to leverage our open-source designs (here) to embed the power of OAK-D into your own products and/or customize the OAK-D-IoT to your exact needs.
