Why customize M5Stack StopWatch Dev Kit?
A flashed M5Stack StopWatch responds to motion, touch and button presses with an animated on-screen companion, without needing a model API at runtime. The motion-sensitive pet firmware runs locally on the badge, without an AI API at runtime.
A good fit for
Badge, display, touch, IMU and haptics. A pet that lives on a motion-sensitive badge.
Not the right fit for
A guaranteed plug-and-play recreation without the listed hardware revisions, accessories and software setup.
Compatibility
- Exact hardware
- M5Stack StopWatch Dev Kit (ESP32-S3)
- Software route
- Firmware and filesystem flashing
- Where code runs
- The motion-sensitive pet firmware runs locally on the badge, without an AI API at runtime.
- Development tools
- A laptop, a coding agent such as Claude Code or Cursor, and the tools listed in the guide.
- Evidence
- Source-reviewed creator project. Not hands-on tested.
Project ideas
- 01A pet that lives on a motion-sensitive badge
Getting started
- 01
Check your model and revision
- 02
Read the creator’s setup
Firmware and filesystem flashing required; runs locally without an AI API. TAVI derives from this project and is held rather than double-counted.
- 03
Start with a reversible test
Follow the linked project source before changing the device. Back up existing configuration, keep credentials private and stop if your hardware differs from the documented version.
Setup & technical references
Starter prompt
Help me plan a pet that lives on a motion-sensitive badge using M5Stack StopWatch Dev Kit. Read https://youcanjustbuildthings.openai.chatgpt.site/projects/submission-15b148cc94a3ce050e840a5302e1824396ae5cb2892d9e60ce04a435f8fb5070 and its supporting sources first. The motion-sensitive pet firmware runs locally on the badge, without an AI API at runtime. Firmware and filesystem flashing required; runs locally without an AI API. TAVI derives from this project and is held rather than double-counted. Confirm my exact hardware and required accessories, explain what is missing, and propose one reversible test. Ask before flashing firmware, changing privileged system settings or moving physical hardware.
Confirm your exact hardware before running device-changing commands.
Common questions
Where does my software run?
The motion-sensitive pet firmware runs locally on the badge, without an AI API at runtime.
What should I check before buying?
Product page. Stock and delivery region are not confirmed. Check exact model and bundle contents with the seller.
What are the setup risks?
Firmware and filesystem flashing required; runs locally without an AI API. TAVI derives from this project and is held rather than double-counted.
