Specification:
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. All‑in‑one AI desktop robot: integrates controller, screen, sensors, servos and battery in a compact table‑top unit.
2. Flexible motion system: 360° pan and 90° tilt servo structure lets the “face” follow people or point to objects.
3. Rich human‑machine interaction: 2.0" touch screen, dual mics, speaker, IR, NFC, touch pads and buttons for multiple control methods.
4. Full IoT development platform: ESP32‑S3 with 16 MB Flash + 8 MB PSRAM, Grove ports, GPIO/UART/I2C and microSD for custom projects.
5. Voice‑based Q&A and smart‑home gateway: works as a voice assistant and front‑end controller for connected devices.
6. Open‑source ecosystem: official documentation, firmware and tutorials available (UIFlow, Arduin, MicroPython, etc.) for secondary development.
