Power RequirementsThe Pi4B requires a good quality USB-C power supply capable of delivering 5V at 3A. If attacheddownstream USB devices consume less than 500mA, a 5V, supply may be GPIO InterfaceThe Pi4B makes 28 BCM2711 GPIOs available via a standard Raspberry Pi 40-pin header. This headeris backwards compatible with all previous Raspberry Pi boards with a 40-way GPIO Pin AssignmentsFigure 3: GPIO Connector PinoutAs well as being able to be used as straightforward software controlled input and output (with pro-grammable pulls), GPIO pins can be switched (multiplexed) into various other modes backed by dedi-cated peripheral blocks such as I2C, UART and addition to the standard peripheral options found on legacy Pis, extra I2C, UART and SPI peripheralshave been added to the BCM2711 chip and are available as further mux options on the Pi4.

Most of these alternateperipheral functions are described in detail in the BCM2711 Peripherals Specification document whichcan be downloaded from the hardware documentation section of the 1 Raspberry Pi 4 Model B DatasheetCopyright Raspberry Pi (Trading) Ltd. Display Parallel Interface (DPI)A standard parallel RGB (DPI) interface is available the GPIOs. This up-to-24-bit parallel interface cansupport a secondary SD/SDIO InterfaceThe Pi4B has a dedicated SD card socket which suports , DDR50 mode (at a peak bandwidth of 50 Megabytes / sec). In addition, a legacy SDIO interface is available on the GPIO camera and Display InterfacesThe Pi4B has 1x Raspberry Pi 2-lane MIPI CSI camera and 1x Raspberry Pi 2-lane MIPI DSI Displayconnector.

7 These connectors are backwards compatible with legacy Raspberry Pi boards, and supportall of the available Raspberry Pi camera and display USBThe Pi4B has 2x USB2 and 2x USB3 type-A sockets. Downstream USB current is limited to approxi-mately in aggregate over the four HDMIThe Pi4B has 2x micro-HDMI ports, both of which support CEC and HDMI with resolutions up Audio and Composite (TV Out)The Pi4B supports near-CD-quality analogue audio output and composite TV-output via a 4-ring TRS A/V analog audio output can drive 32 Ohm headphones Temperature Range and ThermalsThe recommended ambient operating temperature range is 0 to 50 degrees reduce thermal output when idling or under light load, the Pi4B reduces the CPU clock speed andvoltage. During heavier load the speed and voltage (and hence thermal output) are increased. Theinternal governor will throttle back both the CPU speed and voltage to make sure the CPU temperaturenever exceeds 85 degrees Pi4B will operate perfectly well without any extra cooling and is designed for sprint performance -expecting a light use case on average and ramping up the CPU speed when needed ( when loadinga webpage).
