RASPBERRY PI 400 - 4GB RPI4
Raspberry Pi 400 has similar spec as Raspberry Pi 4 Model B 4GB RAM, yet the processor runs at higher clock speed.
The Raspberry Pi 400 keyboard computer does not come with CSI (camera interface) nor DSI (Display interface).
If you need a camera, you can always get a USB webcam and the display can come from a monitor or TV via micro-HDMI
Raspberry Pi 400 comes with a similar processor to Raspberry Pi 4 Model B, clocked at a faster speed, 1.8GHz.
This is 20% faster than 1.5GHz on Raspberry Pi 4 Model B.
It never disappoints any of us! With the faster processor speed, groundbreaking multimedia performance, and connectivity,
and RAM of 4GB, you will be blown away with its performance! Now, this powerful single-board computer is embedded in a Keyboard, making it more convenient for everyone.
Raspberry Pi 400’s processor (BCM2711C0) is clocked at 1.8GHz (factory default maximum clock speed), but it does not require any additional cooling even though the motherboard is enclosure under the keyboard. We have run a stress test on this new computer for 20 minutes with a full load on every core, the CPU temperature raises from ~35ºC but stays under 55ºC. Amazing!
The secret recipe of good thermal performance is a cleverly designed aluminum heatsink plate on top of the CPU (underneath the keypads) that ensure Raspberry Pi 400 always stays cool.
