Maixduino - AI Accelerated Single Board Computer, RISC-V AI, Arduino Form Factor and ESP32 Wireless Module
MAIX is a specialized series of Sipeed products designed to work with AI. Unlike conventional CPs, specialized CPs can work faster and with lower energy costs. Based on the MAIX module, Maixduino is a RISC-V 64 development board for AI (artificial intelligence) and IoT (internet of things) applications. The Maixduino is based on the Kendryte K210 RISC-V AI SoC and, unlike other Sipeed MAIX development boards, is in the Arduino Uno form factor, with an ESP32 module to support WiFi and Bluetooth.
The Maixduino development board was provided by Seeed Studio , the kit retails for $ 23.90 plus shipping and includes an OV2640 camera module, a 2.4-inch TFT display, and the Maixduino board itself.
Maixduino can be programmed with MaixPy IDE (MicroPython), Arduino IDE, OpenMV IDE and PlatformIO IDE, and also supports Tiny-Yolo, Mobilenet and TensorFlow Lite deep learning platforms with QVGA @ 60fps or VGA @ 30fps image identification. Maixduino makes Arduino IDEs and libraries to support the Maix series of development boards (k210 chips), making it easy to use the large number of existing open source Arduino libraries to quickly develop your projects.
To connect, you will need a USB 2.0 to Type C cable or adapter, the cable will be used to power and program both the K210 and ESP32 via the dual-channel CH522 chip: the first channel is for the K210, and the second for the ESP32.
Typical applications:
- Smart Home applications such as cleaning robots, smart speakers, electronic door locks, home monitoring;
- Medical industry applications such as assistive diagnostics and treatment, medical image recognition, emergency alarms;
- Smart Industry applications such as industrial equipment, smart sorting, electrical equipment monitoring;
- Educational applications such as educational robots, intelligent interactive platforms, learning effectiveness testing;
- Agricultural applications such as agricultural monitoring, pest and disease monitoring, automated control, etc.
