No card reader? You can still flash CardputerZero through USB Boot.

Use rpiboot to make the microSD card inside CardputerZero appear as a storage device on your computer, then flash the system image with M5 Imager.

This method works when you do not have a card reader, but it is slower. For the best experience, we still recommend using a card reader.

CardputerZero as a compact AI voice interface.

This demo runs Xiaozhi, with voice input through the built-in microphone, responses shown on screen, and audio played through the speaker.

Developers can use it as a starting point to connect their own AI services, assistants, or custom workflows.
