Product features:
1) The processor is faster; The CPU is upgraded to 1.5G 4-core 64-bit, and the computing speed of the CortexA72 architecture is more than 3 times that of Pi 3B+.
2) Three kinds of memory options; provide 2GB, 4GB, and 8GB three kinds of memory options, according to
You must select the corresponding memory; 2GB is suitable for users who need to configure a graphical user interface or surf the Internet, such as watching videos on a PC, deploying a micro-network server, etc. 4GB and 8GB are suitable for users with more complex multitasking, such as dual-screen 4K video playback, AI visual deep learning, etc.
3) 5.0 wireless Bluetooth; Bluetooth is upgraded to 5.0 BLE, low power consumption, no delay, more stable and faster transmission.
4) 4K high-definition dual display; support up to 4K high-definition dual display through 2 HDMI ports, and enjoy beautiful images quickly.
5) Gigabit Ethernet port; Ethernet is upgraded to Gigabit, which is faster and more stable than Raspberry Pi 3b+.
Compared with 3B+, Pi4’s network card chip generates less heat and is smaller in size, and many surrounding components may cause a short circuit, so using a heat sink for the network card is not recommended. In addition, compared to 3B +, the performance is improved by more than 3 times, with rich multimedia, abundant memory and excellent connectivity. The newly introduced high-speed USB 3.0 management chip has high heat generation and is close to the CPU and memory. It is recommended to stick a heat sink for overall heat dissipation.
