Exact generation/RAM not disclosed; the experiment runs host services on macOS. - Required: USB-C data cable. A charge-only cable cannot flash firmware. 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: 2.4 GHz Wi-Fi network. - Required: Device power supply. Reuse the Mac mini supply and handheld charging arrangement. ## Compatibility and cautions - Advanced setup with a separate Mac mini. The agent has broad host access; spoken confirmation is prompt-based, not a security boundary. The creator reset the device after the experiment. - ADV uses TCA8418 keyboard control and ES8311 audio; original Cardputer drivers are not interchangeable. - 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+Cardputer+ADV) — Search destination only; matching listing NOT verified Search fallback only.
