Raspberry Pi pi400, a keyboard and a computer!
This product is not only a Raspberry Pi development board, but also can be used as a computer. Of course, it is not a simple package of Raspberry Pi 3b. For this reason, the manufacturer redesigned the circuit and pcb. You only need to have an HDMI cable, a 5V power adapter and a mouse, and connect to the monitor, and the Raspberry Pi 400 becomes a standard desktop computer.
Is it super simple, can be used as an ordinary computer, or as a development board with higher performance than 4b. The important thing is that there is a 40pin GPIO interface, and because of the redesigned heat sink, it does not need to install a cooling fan for its own heat dissipation performance.
Welcome to shop and buy, currently there are two versions of US and DE on sale
