Overview
Raspberry Pi 4 Model B is the latest product in the popular Raspberry Pi range of
computers. It offers ground-breaking increases in processor speed, multimedia
performance, memory, and connectivity compared to the prior-generation
Raspberry Pi 3 Model B+, while retaining backwards compatibility and similar
power consumption. For the end user, Raspberry Pi 4 Model B provides desktop
performance comparable to entry-level x86 PC systems.
This product’s key features include a high-performance 64-bit quad-core
processor, dual-display support at resolutions up to 4K via a pair of
micro-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 reduced
compliance testing, improving both cost and time to market.

WARNINGS
•
This product should only be connected to an external power supply rated at 5V/3A DC or 5.1V/ 3A DC
minimum
1
. Any external power supply used with the Raspberry Pi 4 Model B shall comply with relevant
regulations 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 case
should not be covered.
This product should be placed on a stable, flat, non-conductive surface in use and should not be
contacted by conductive items.
The connection of incompatible devices to the GPIO connection may affect compliance and result in
damage to the unit and invalidate the warranty.
All peripherals used with this product should comply with relevant standards for the country of use
and be marked accordingly to ensure that safety and performance requirements are met. These
articles include but are not limited to keyboards, monitors and mice when used in conjunction with
the Raspberry Pi.
Where peripherals are connected that do not include the cable or connector, the cable or connector
must offer adequate insulation and operation in order that the relevant performance and safety
requirements are met.

SAFETY INSTRUCTIONS
To 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 operation
at normal ambient room temperatures.
Take care whilst handling to avoid mechanical or electrical damage to the printed circuit board
and connectors.
Avoid handling the printed circuit board whilst it is powered and only handle by the edges to minimise the
risk of electrostatic discharge damage.
