 - And of course our GitHub community. Your PRs are a very important part of this firmware and open-source development.

 The amount of work done on this project is huge and we need your support, no matter how large or small. Even if you just say, "Thank you Unleashed firmware developers!" somewhere. Doing so will help us continue our work and will help drive us to make the firmware better every time.
 Also, regarding our releases, every build has and always will be free and open-source. There will be no paywall releases or closed-source apps within the firmware. As long as I am working on this project it will never happen.

+ * 14 -> 15 (USART RX to LPUART TX)
+ *
+ * What this application does:
+ *
+ * - Enables module support and emulates the module on a single device
+ *   (hence the above connection),
+ * - Connects to the expansion module service, sets baud rate,
+ * - Starts the RPC session,
+ * - Creates a directory at `/ext/ExpansionTest` and writes a file
+ *   named `test.txt` under it,
+ * - Plays an audiovisual alert (sound and blinking display),
+ * - Waits 10 cycles of idle loop,
+ * - Stops the RPC session,
+ * - Waits another 10 cycles of idle loop,
+ * - Exits (plays a sound if any of the above steps failed).
