Flipper One operates in several modes depending on its hardware state and the type of software loaded. The display and LED indicate the current mode.

***

### Power OFF

The device is completely powered down. The main CPU and MCU are fully off, and the display is not active. This mode is used for long-term storage, shipping, and maximum power saving.

***

### MCU Mode

Only the low-power Microcontroller Unit (MCU) is active. The device works as a power bank and displays basic info on the screen. Two GPIO pins (M40, M41) are available in this mode.

***

### Boot Menu

The device is running the U-Boot menu with available Flipper OS boot profiles. The main CPU is powered on, but the operating system has not yet started.

### How to switch modes

Depending on the current operating mode, the Power button :inlineImage[]{src="https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/0cCRZZDNse9bcy9pxIQ9q_uipowerbutton.png" alt caption} switches the mode or opens the Power menu.

**Power menu** — a modal window with the available power and boot options.
