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.

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.
