== Technical overview ==
* The Raspberry Pi 400 is a keyboard-style mini computer featuring a 1.8 GHz ARM Cortex-A72 CPU, 4 GB LPDDR4 RAM, dual-band Wi-Fi (2.4/5 GHz) and Bluetooth 5.0.
* Availability: The kit exists in UK and US versions; both are stated to be compatible in hardware and software.
* Raspberry Pi 400 interfaces: Type-C power input (requires 5 V/3 A adapter), 40-pin GPIO header, micro SD card slot, two micro HDMI ports (up to 4Kp60), Gigabit Ethernet, 2× USB 3.0 and 1× USB 2.0.
* Kit dimensions: 286 mm × 122 mm × 23 mm (maximum).
* The 7-inch LCD uses an IPS panel with native resolution 1024×600; the resolution can be configured in software up to 1920×1080.
* Touch capability: capacitive touch panel with toughened glass (case version only).
* PC compatibility: Windows 7/8/8.1/10/11; touch is auto-detected via USB; HDMI audio is available through the 3.5 mm jack.
* VGA input is supported but requires a separate mini-HDMI-to-VGA cable.
* When used with a Raspberry Pi, the LCD resolution must be manually configured in config.txt, otherwise the display will not work.
* Supported operating systems on the Raspberry Pi: Raspberry Pi OS, Ubuntu, Kali, and Retropie.

'''Commands and examples – verify before use:'''
<syntaxhighlight lang="text">
xrandr
xinput
xinput map-to-output <touch ID> <HDMI-ID>
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart
</syntaxhighlight>

== Notes and version constraints ==
* Exact ID values for xinput/xrandr depend on the specific installation and must be verified locally.
* Some PCs do not support HDMI hot-plug; a reboot may be required.
* LCD flicker can occur due to insufficient USB power supply; connect an external 5 V/2 A power adapter to the DC port if needed.
* The mini-HDMI-to-VGA cable must be purchased separately.
* To persist the touch configuration, add the line to the autostart file and then reboot.
* The described key functions refer to the case version; without the case, different labels apply.
