CDC Badge OS

Intermediate

The pages in this section go past everyday use and into the controls a power user reaches for: the WASM plugin runtime, the serial console, the Expert menu, the language system, the on-device file and NVS tools, and the Python helpers in tools/. Each page is verified against the firmware source.

  • Plugins - install and run sandboxed WASM plugins.
  • Serial console - the USB CDC command shell.
  • Expert menu - hardware info, module control, backup, duress PIN, secure-element cache maintenance and bootloader entry.
  • Languages - how the English fallback and the on-device language overlays work, and how to add a language.
  • File storage & NVS tools - the vFAT file explorer and the NVS browser/editor.
  • Companion tools - the host-side scripts in tools/.
