About M5Stack
M5Stack is a Shenzhen-based open-source hardware company founded in 2017, best known for its modular ESP32 development ecosystem used by hundreds of thousands of makers, educators and IoT engineers worldwide. With Stack-chan — co-created with the open-source community — M5Stack moved into consumer robotics, packaging the flagship CoreS3 development kit (ESP32-S3, 2.0" capacitive touch display, 0.3 MP camera, 9-axis IMU, dual mics) into a kawaii two-servo body with NFC, IR and 12 RGB LEDs. The XiaoZhi AI agent and StackChan World iOS app deliver video calls and remote avatars out of the box, while full Arduino and UiFlow2 support keeps the platform fully programmable. After a successful Kickstarter campaign, Stack-chan is now shipping in production at $99 from shop.m5stack.com — the most accessible AI desktop companion ever sold, and the clearest sign that maker-grade hardware can compete with closed commercial robots on price and openness.
