 dfu-util can be used to communicate with DFU (device firmware upgrade) enabled devices.
-One example is the Leaflabs [[:boards:maple|Maple mini]].
+Examples include the Leaflabs [[:boards:maple|Maple mini]] [[:tools:maple|boot loader]] and the [[:boards:longan|Longan Nano]].
+Be sure to have the latest version installed from at least 2020 if you intend to use
+the [[:boards:longan|Longan Nano]] which may not work correctly otherwise.
