-**Hardware:**
-
-.. todo:: Add links to any specific hardware product page(s), or category page(s).
-  Use unordered list & hyperlink rST inline format: "* `Link Text <url>`_"
-
 **Software and Dependencies:**
 
 * Adafruit CircuitPython firmware for the supported boards:
   https://circuitpython.org/downloads
 
-.. todo:: Uncomment or remove the Bus Device and/or the Register library dependencies
-  based on the library's use of either.
