Advantage:
In comparison with other K210 development board, M5stack K210 Camera features more hardware resources such as a speaker, Microphone, LCD screen, gyroscope, and wireless network implementations. 
The K210 includes two 64-bit RISC-V CPU cores, each with a built-in independent Float Point Unit.
KPU high-performance Convolutional Neural Network hardware accelerator. The primary functions of the K210 are machine vision and hearing, which includes the KPU for computing convolutional neural networks and an APU for processing microphone array inputs.
The K210 features a Fast Fourier Transform (FFT) Accelerator for high-performance complex FFT calculations. As a result, for most machine learning algorithms, the K210 has the high-performance processing power.
