Sipeed M1W AI Module - module with Kendryte K210 and ESP8285 system

Description

Sipeed M1W AI Module is a Sipeed module designed to run artificial intelligence (AIoT). It provides high performance with low physical load and power, enabling the implementation of precise artificial intelligence, and the competitive price allows it to be used on any IoT device. Sipeed MAix is not only a device, but also a comprehensive hardware and software infrastructure facilitating the implementation of solutions based on artificial intelligence.

The module is designed in the form of a small plate with pads for surface mounting. Provides a wide range of peripheral systems: FPIOA, UART, GPIO, SPI, I2C, I2S, WDT, TIMER, RTC etc. The board has the ESP8285 WiFi module, an external Flash memory and a DC-DC converter. The module was closed in a tin housing. A connector for an external WiFi antenna has been led out.

MAIX supports the original standalone SDK, FreeRTOS SDK based on C/C++. Has support in the form of support in Micropython.

MAIX can be used for many industrial applications such as predictive maintenance, anomaly detection, machine vision, robotics, voice recognition and many more. It can be used in production, factories, healthcare, retail and transport.
