Raspberry Pi 4 ComputerModel BPublished in June 2019by Raspberry Pi Trading Ltd.www.raspberrypi.org

OverviewRaspberry Pi 4 Model B is the latest product in the popular Raspberry Pi range ofcomputers. It offers ground-breaking increases in processor speed, multimediaperformance, memory, and connectivity compared to the prior-generationRaspberry Pi 3 Model B , while retaining backwards compatibility and similarpower consumption. For the end user, Raspberry Pi 4 Model B provides desktopperformance comparable to entry-level x86 PC systems.This product’s key features include a high-performance 64-bit quad-coreprocessor, dual-display support at resolutions up to 4K via a pair ofmicro-HDMI ports, hardware video decode at up to 4Kp60, up to 4GB of RAM,dual-band 2.4/5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0,and PoE capability (via a separate PoE HAT add-on).The dual-band wireless LAN and Bluetooth have modular compliance certification,allowing the board to be designed into end products with significantly reducedcompliance testing, improving both cost and time to market.2Raspberry Pi 4 Model B Product Brief

Physical SpecificationsNote: all dimensions in mmWARNINGS This product should only be connected to an external power supply rated at 5V/3A DC or 5.1V/ 3A DCminimum1. Any external power supply used with the Raspberry Pi 4 Model B shall comply with relevantregulations and standards applicable in the country of intended use. This product should be operated in a well-ventilated environment and, if used inside a case, the caseshould not be covered. This product should be placed on a stable, flat, non-conductive surface in use and should not becontacted by conductive items. The connection of incompatible devices to the GPIO connection may affect compliance and result indamage to the unit and invalidate the warranty. All peripherals used with this product should comply with relevant standards for the country of useand be marked accordingly to ensure that safety and performance requirements are met. Thesearticles include but are not limited to keyboards, monitors and mice when used in conjunction withthe Raspberry Pi. Where peripherals are connected that do not include the cable or connector, the cable or connectormust offer adequate insulation and operation in order that the relevant performance and safetyrequirements are met.SAFETY INSTRUCTIONSTo avoid malfunction or damage to this product please observe the following: Do not expose to water, moisture or place on a conductive surface whilst in operation. Do not expose it to heat from any source; Raspberry Pi 4 Model B is designed for reliable operationat normal ambient room temperatures. Take care whilst handling to avoid mechanical or electrical damage to the printed circuit boardand connectors. Avoid handling the printed circuit board whilst it is powered and only handle by the edges to minimise therisk of electrostatic discharge damage.14 A good quality 2.5A power supply can be used if downstream USB peripherals consume less than500mA in total.Raspberry Pi 4 Model B Product Brief
