seeed studio Raspberry Pi 400 Personal Computer in Keyboard Form Cortex A72 CPU Dual 4K HD - (Only keyboard)

The Raspberry pi 400 is essentially a Raspberry Pi 4 Model B 4GB built into the keyboard.

The difference is that the raspberry pi 400 doesn't have CSI and DSI interfaces for cameras and official touch screens.

However, compared with the raspberry pi 4 Model B 4GB, the raspberry pi 400 has faster CPU and better heat dissipation performance.

As we all know, raspberry pi 4 will become very hot in use, but the storage speed of raspberry pi 400 is 1.8 GHz, 300 MHz higher than that of standard raspberry pi 4, and raspberry pi 400 has built-in large heat sink, so it often has better heat dissipation performance on the premise of ensuring performance.
