Motor Safety: Do not forcibly rotate any movable parts connected to the motors by hand when you are unsure whether the motors are powered and under control, as this may cause hardware damage. Motion Angle Notice: The movement angle of the StackChan Y-axis servo (vertical direction) is recommended to be controlled within 5 ~ 85°. Operating at extreme angles may cause servo stall and permanent damage. No angle restriction is required for the X-axis.
Introduction:
StackChan is a super kawaii AI desktop robot co-created by M5Stack and the user community. It uses the M5Stack flagship IoT development kit CoreS3 as its main controller, powered by an ESP32-S3 SoC featuring a 240 MHz dual-core processor, with 16MB Flash and 8MB PSRAM onboard, and supporting Wi-Fi and BLE. The main unit also integrates a 2.0-inch capacitive touch display with a high-strength glass cover, a 0.3 MP camera, a proximity & ambient light sensor, a 9-axis IMU (accelerometer + gyroscope + magnetometer), a microSD card slot, a 1W speaker, dual microphones, and power/reset buttons. The robot body, connected to the main unit, includes a USB-C interface for power and data, a 550 mAh battery, two feedback servos (360-degree continuous rotation on the horizontal axis and 90-degree movement on the vertical axis), two rows totaling 12 RGB LEDs, infrared transmitter and receiver, a three-zone touch panel, and a full-featured NFC module. The factory firmware is feature-rich, including an AI Agent, lively and expressive animations, ESP-NOW wireless remote control, and online app downloads. It can connect to a mobile app for video viewing, remote avatar control, and more, and also supports online updates (OTA). The product also supports programming via Arduin, UiFlow2, and other methods, and can connect to various expansion units in the M5Stack ecosystem, making it easy to implement a wide range of custom functions.
Features:
1. AI desktop companion: voice‑based question & answer, animated facial expressions and interactive touch control.
2. All‑in‑one IoT development kit: ESP32‑S3 core, NFC, sensors and Grove ports for rapid prototyping and smart‑home projects.
3. Pan‑tilt robotic head: built‑in 360° pan and 90° tilt servos to create expressive movements and camera tracking.
4. Rich audio & video: front 0.3 MP camera, dual microphones and 1 W speaker for voice interaction and media playback.
5. Flexible expansion options: microSD slot, GPIO, UART, I2C and LEGO‑compatible mounting holes for custom builds.
6. Portable power design: integrated 550mAh rechargeable battery and USB‑C charging/data interface.
