## Hardware Reset Button
|
|
|
|
The Ploopy Nano has a handy bootloader reset mechanism: two via pins on the board, designated by the reference designator `MCU.J.X BOOTLOADER`. If you stick an uninsulated paperclip or a pair of metal tweezers into both holes and plug in the Nano, it will start in bootloader mode.
|
|
|
|
## Revisions
|
|
|
|
Occasionally, new revisions of the PCB will be released. Every board comes with a designator that looks something like `R1.001`.
|
|
|
|
Match the firmware that you flash onto the board with the designator on the board.
|
|
|
|
## Fuse settings
|
|
|
|
When flashing the bootloader, use the following fuse settings:
|
|
|
|
