Frequently Asked Questions

Does the Raspberry Pi 400 come with a mouse, monitor or accessories?

No. Seeed studio ships the keyboard unit alone; the listing states there is only a keyboard in the package, so you supply the mouse, monitor and cabling yourself.

How much faster is the Pi 400 than the Raspberry Pi 4?

The Pi 400 runs its quad-core 64-bit Arm Cortex-A72 at 1.8GHz versus 1.5GHz on the Raspberry Pi 4. Seeed credits that 300MHz gap for more stable operation and faster large-file read and write speeds.

Can the Raspberry Pi 400 run two 4K monitors at the same time?

Yes. The two HDMI ports on the back support dual 4K high-definition output, which is why it works as a two-screen desk setup.

Do I need a Wi-Fi or Bluetooth adapter with it?

No. Dual-band 2.4GHz/5GHz Wi-Fi and Bluetooth 5.0 are built into the keyboard, so wireless networking and wireless peripherals work without a USB dongle.
