CanMV K230

What is CanMV?

The CanMV open source project is officially created and maintained by Canaan. It is an open source project that ported MicroPython to Canaan's edge computing AI chip K210/K230 (a 64-bit dual-core RISC-V with hardware FPU and convolution accelerator). The project aims to create a low-cost, scalable, Python-driven AI artificial intelligence module.

In other words, if you are familiar with Micropython or Python, you can complete a large number of machine vision, machine hearing and deep learning applications through the CanMV project in a very short time.

CanMV K230 Development Board

01Studio CanMV K230 AI development board is based on Canaan Technology's edge computing chip K230 (RSIC-V architecture, 64-bit dual-core) and the CanMV open source project.
