## 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:

| Fuse     | Setting     |
|----------|-------------|
| Low      | `0x5E`      |
| High     | `0x99`      |
| Extended | `0xC3`      |
