## Surface mount pads
## Jumper pads

Some boards in the Nano family have jumper pads that can be soldered or cut to reroute connections and modify the board's default behavior.

### 3.3V pads

Some Nano boards that operate at 3.3 V have an exposed trace that can be cut to bypass the step down converter. This disables the USB port, but allows you to power the board directly with a 3.3 V source for lower power consumption.

Some boards in the Nano family have pads that can be soldered or cut to change the board's configuration.
