MaixCAM User Guide

1. Introduction to MaixCAM

MaixCAM is a hardware product designed for the rapid deployment of AI vision, audio, and AIOT applications. It serves as a platform for quickly verifying product prototypes and moving to mass production, featuring a powerful yet cost-effective processor with integrated cameras, screens, WiFi, and a complete, easy-to-use software ecosystem.

Target Use Cases and Audience:

AI Algorithm Deployment: AI engineers can quickly deploy their AI models on real hardware (MaixCAM) using easy-to-use model conversion tools and SDKs.
STEM Education: With the MaixPy SDK and development tools, teachers can focus on teaching while students quickly get hands-on experience without needing to develop hardware or software.
University Research and Education: Comprehensive documentation and tutorials provide learning paths for students at all levels, while RISC-V and AI technologies offer tools for research.
Prototyping for Makers and Engineers: Well-designed hardware, extensive peripherals, and easy-to-use software let you quickly turn ideas into reality without getting bogged down by basic development tasks.
Enterprise Product Upgrades and Deployment: Quickly deploy products without high R&D costs, or add AI vision to existing equipment for smart enhancements.
Competitions: MaixCAM + MaixPy + MaixCDK provide rapid innovation for competitions. The platform has already been used to win various awards.
