Sipeed Maixduino for RISC-V AI+IoT - evaluation kit with Kendryte K210 and ESP32

Description

Sipeed Maixduino for RISC-V AI + IoT is a set with the 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.

Sipeed Maixduino for RISC-V AI + IoT is an evaluation kit with RISC-V Dual Core 64bit chip clocked at 400MHz and WiFi ESP32 module. Equipped with a USB-UART converter, OV2640 camera, MEMS microphone, microSD card slot as well as an audio converter and a connector for the display. The set is compatible with Arduino Uno Rev3.

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.
