🍓【Powful CPU】The CPU of the Raspberry Pi 4 Model B adopts the latest ARM Cortex-A72 architecture, which is also used in high-performance smartphones, and has evolved into a real PC.The operating clock has been changed from Pi3's 1.2GHz to 1.5GHz, and the speed has become a different dimension with the updated architecture. | 🍓【Video output/GPU】The on-board GPU of the Raspberry Pi 4 supports 4Kp@60 and newly supports H.265 decoding, OpenGL ES 3.0, etc.As for the video output, two micro HDMIs with smaller connectors are installed, and the Raspberry Pi 4 also supports dual screen output. | 🍓【USB 3.0】With a new SoC, the speed of the Raspberry Pi 4 around I/O has been improved, and finally USB 3.0 is supported.USB boot is faster and more convenient. | 🍓【network&Bluetooth】Gigabit Ethernet (wired LAN) has also been significantly speeded up from 300Mbps of Pi 3B + to 1000Mbps (logical value).In addition, Bluetooth supported version has been upgraded to 5.0, and the transfer speed of Pi 4 has been doubled. | 🍓【Power input connector】The power input connector of the Raspberry Pi 4 has been changed to USB type C. It is easier to use than micro USB and can supply a larger current reliably.The power requirement of Raspberry Pi 4 Model B is 5V 3.0A, which is higher than the previous model.
