# Sonoff Mini
The Mini is, as the name implies, a very small device, designed to be hidden where there's only supposed to be cables. Since it's not supposed to be visible, it's also designed to easily attach an external button.
If you flash custom firmware on the Mini, several extra GPIO's becomes available. Most noticable is probably the OTA jumper pins, which are very easy to use, you may not even need to solder.
