I bought this and after it shipped I looked at reviews and the questions then I got worried no accessories came with it. But I got everything that was listed which includes The Pi 400 built into the keyboard, USB wired mouse, Micro SD 16gb pre-loaded Pi OS, power supply, & micro-HDMI to HDMI. It even comes with a book to teach you about Pi’s so I would recommend this and you can even wipe the Pi OS to put anything on it such as Kali.
