+/** @addtogroup debug Debug UART
+  * @brief This section covers functions related to the debug UART, available on
+  *        pin D1 of the 9-pin connector.
+  * @warning These functions were used early on in development, before the TinyUSB
+  *          CDC was implemented. You can now print debug messages to the USB console
+  *          using printf, rendering this bit irrelevant. These methods will likely
+  *          be refactored out in the future, in favor of a more full-featured UART
+  *          on the nine-pin connector.
