 explanation, with a lot of details that are likely only interesting to
 a few. If you just want to get the rough idea, skim this article. If
 you want to start hacking on the bootloader, get in touch with us to

 Maple Rev3

 Maple Rev 3 takes a completely different tack, more along the lines of
 Arduino.  In Rev 3, the device resets into bootloader mode, which

 However, it is no longer possible to upload code at will, since there
 is no bootloader quietly listening in the background. Instead you have
 to reset the board, then initiate a DFU transaction. This reset is
 performed automatically by the IDE by sending a command over the USB
