M5Stack A180 StackChan Body

Introduction

The M5Stack A180 StackChan Body is a replacement body module for the StackChan AI desktop robot platform. It combines motion, lighting, touch input, infrared communication, NFC, battery power, and expansion connectivity in a compact robotics enclosure.

Part Description

The StackChan Body provides the core physical and interactive hardware for a StackChan robot. It includes a USB-C interface for power and data, along with an integrated 550mAh battery for portable operation.

Two feedback-compatible servos allow the robot to create expressive mechanical movement, such as head rotation, tilting, or gesture-like motions. A set of 12 RGB LEDs adds configurable visual feedback for status displays, animated effects, emotions, or notifications.

For interaction and sensing, the module includes a three-zone capacitive touch panel, an infrared transmitter and receiver, and NFC capability. The touch zones can support user controls such as taps or gestures, while the IR hardware can communicate with compatible remote controls or nearby devices. NFC enables tag-based identification, triggers, or user interactions.

Two Grove interfaces provide straightforward expansion options for connecting additional sensors, actuators, and peripheral modules.
