In terms of software, Banana Pi points to the CanMV GitHub repository, which contains resources for the K230 SDK, on top of that they mention that the KPU supports various neural networks including ResNet50, MobileNet_V2, and YOLOv5 which makes this device suitable for image and video processing, audio analysis, and general AI work.

Previously Banana Pi released Banana Pi BPI-M4 Zero which also has an identical form factor but is built around an Allwinner H618 SoC, the main difference between the two is that the BPI-M4 Zero is a general-purpose SBC with various multimedia and connectivity options, making it a versatile choice for DIY projects and general computing tasks. The BPI-CanMV-K230D-Zero on the other hand is optimized for AI and machine learning, with specialized hardware for neural network processing and a focus on IoT and AI-driven applications. We have also written about various SBCs and development boards from Banana Pi including Banana Pi BPI-M1S, the Banana Pi BPI-CM5 Pro, the Banana Pi BPI-WiFi6, and others.

The Banana Pi BPI-CanMV-K230D-Zero can be purchased from the Banana Pi AliExpress store for $28.90 and on Amazon for $39.90. Some additional information about the board can be found on the Wiki page.
