Panda AI OS Simulator lets you try a Panda-compatible e-paper reader in your browser. Device Studio runs a simulator-targeted guest path through QEMU/WASM and shows the guest framebuffer alongside board controls, serial output, hardware keys, and a Virtual SD card. Open the live demo or watch the 4:44 walkthrough. The browser path does not model physical e-paper ghosting, RF, power, battery, or USB behavior. Simulator, guest, ROM, and dependency licenses remain separate.
