Raspberry Pi 4 Model B use Type-C interface, support larger current input (5V 3A), configure dual-frequency 802.11ac 5G/2.4G network, and support I2C, SPI and UART. The 4GB memory version is suitable for users who do more multitasking, such as dual-screen 4K video playback, AI visual deep learning, etc., to meet the needs of most buyers. From the previous standard HDMI interface to two micro HDMI interfaces, it supports the output of dual HD 4K video. The USB connection mode is enhanced. Two USB ports are upgraded to 3.0 version, the transmission speed is increased by about 10 times, and Bluetooth is upgraded to 5.0BLE, which makes the performance more stable and meets your low power consumption requirements. Raspberry Pi 4 Model B CPU upgrade 1.5G 4-core 64-bit, Cortex-A72 architecture operation speed is more than 3 times that of Pi3B.
