The StackChan is an open, hackable desktop robot built on M5Stack's CoreS3 board: an ESP32-S3 dual-core chip with 16MB flash and 8MB PSRAM, Wi-Fi and BLE, a 2.0-inch capacitive touch screen, a 0.3MP camera, dual microphones, a 1W speaker and 12 RGB LEDs. Two feedback servos give it 360-degree horizontal and 90-degree vertical motion, and it adds proximity and ambient light sensing, a 9-axis IMU, NFC, an IR transmitter and receiver, and a three-zone touch panel. It suits makers and tinkerers who want an expressive robot they can program, not a finished consumer assistant. Against plug-and-play desktop robots, it trades polish for open hardware and community projects. Owners like the engineering and the way it juggles servos, camera, mics and LEDs at once, but say the AI side feels fragmented and the motion stops in standby.

Buyers rate it highly and praise the hardware engineering that packs CoreS3 into an expressive desktop body. Geeks say it works well like other M5Stack products and handles servos, camera, microphone array and LED matrices at once. Complaints focus on fragmented AI support and thin content sources.
StackChan is an AI desktop robot co-created by M5Stack and its user community. It uses the M5Stack CoreS3 as its main controller, built on an ESP32-S3 SoC with a 240 MHz dual-core processor, 16MB Flash and 8MB PSRAM. It supports Wi-Fi and BLE.
The main unit has a 2.0-inch capacitive touch display with a high-strength glass cover. It also has a 0.3 MP camera, a proximity and ambient light sensor, a 9-axis IMU, a microSD card slot, a 1W speaker, dual microphones, and power and reset buttons. The robot body adds a 550 mAh battery, two feedback servos, 12 RGB LEDs, an infrared transmitter and receiver, a three-zone touch panel and an NFC module.
The factory firmware includes an AI Agent, expressive animations, ESP-NOW wireless remote control and online app downloads. A mobile app connects for video viewing and remote avatar control. The robot also supports online (OTA) updates.
