Example requires a USB-A host port. If your computer has only USB-C, use an appropriate USB-C data cable instead. Reuse the device’s included cable where possible; this is not a standalone power-supply recommendation. - Required: External USB power bank. Creator explicitly used this because the battery module was missing; capacity/model not specified. - Tool: Computer for setup. - Required: Wi-Fi network. ## Compatibility and cautions - Wi-Fi, paid cloud services, firmware flashing and a separately built calendar service are required; demonstrated setup uses an external power bank. - SE version is sold without the battery bottom used by some Core kits. Manufacturer confirms USB-C, ES7210 microphone inputs and no battery bottom. The power bank remains the documented demo route. - Source-reviewed, not independently hardware-tested. Confirm the model, revision and recovery process before changing device software. ## Buy [Search Amazon (unverified)](https://www.amazon.com/s?k=M5Stack+CoreS3+SE) — Search destination only; matching listing NOT verified Search fallback only.

Manufacturer confirms USB-C, ES7210 microphone inputs and no battery bottom. The power bank remains the documented demo route. 2. **Read the creator’s setup**: Wi-Fi, paid cloud services, firmware flashing and a separately built calendar service are required; demonstrated setup uses an external power bank. 3. **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. ## Coding-agent project brief Help me plan record dreams on a bedside touchscreen using M5Stack CoreS3 SE. Read https://youcanjustbuildthings.openai.chatgpt.site/projects/submission-76ded4f1a1107d49906050e4d5357c551916871062f47d2ef5f373c27271e2d8 and its supporting sources first. Recording and screen firmware runs on CoreS3 SE; transcription and image generation depend on separate services. Wi-Fi, paid cloud services, firmware flashing and a separately built calendar service are required; demonstrated setup uses an external power bank. 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. ## Common questions ### Where does my software run?
