Description
The 4GB version of Raspberry Pi 4 Model B is one of the newest and most powerful members of the fourth-generation Raspberry Pi family from the Raspberry Pi Foundation which is the fastest board released to date. Whilst the Pi 4 looks similar in shape and size to previous boards, it has been re-engineered and enhanced to be more capable and efficient than ever before, allowing it to contend with a desktop PC experience.
Details
Speedier Processor
The new model is a high-performance general-purpose computer, incorporating an improved quad-core 64-bit ARM Cortex-A72 CPU to rival desktop computers. For the first time, the Pi 4 is available in a choice of memory sizes, so with up to 4GB of RAM (LPDDR4), you will see your Pi being able to carry out much more complicated tasks easily.
Improved Networking
With true Gigabit Ethernet and PoE capability (requires additional PoE HAT); 2.4GHz and 5GHz 802.11b/g/n/ac Wi-Fi and Bluetooth 5.0 with up to four times the range of the old specification. Together these make the Raspberry Pi 4 Model B board an ideal fit for your next SBC-based IoT project.
Upgraded USB Capacity and Power
Pi 4 has four USB ports, two USB 2.0 ports two of which have been upgraded to USB 3.0. The board has a USB Type-C connector for power input, instead of the Micro USB connector the Raspberry Pi 3 had, so you can consolidate your cable collection. The headphone jack has made a return too!
Dual Video Output
Two micro-HDMI ports, replace the single full-size HDMI connector on previous versions, allowing the Pi 4 to support 2 4k monitors. The Pi’s hardware decoding has also been improved to allow it to decode 4K video at 60 frames per second using HEVC encoding.
Backward Compatible
You don’t have to worry about the Pi 4 Model B not working with any of your existing pi projects, as the 40-Pin GPIO header and software are fully backward-compatible.
Getting Started Checklist:
There is an abundance of learning materials, projects, and accessories available for your Pi, but to get started here are the essentials:
- A keyboard, mouse, and display
- Cables to connect to a display/displays
- A USB-C power supply
- The operating system, either picks up a preloaded microSD card or download the latest version of NOOBS for the Raspberry Pi 4 from the Pi Foundation

Communication in Raspberry Pi 4
Raspberry Pi is equipped with 4 popular communication interfaces, available in a traditional PC. The main ones are:
- 2 microHDMI ports for simultaneous connection of two videos receivers even in 4K.
- 2 USB 3.0 and 2 USB 2.0 ports, which can connect peripheral devices. USB 3.0 provides fast transfer from the external drive. The use of an extra USB Hub allows you to add additional connectors.
- Ethernet connector, for connection to the cable network at speeds up to 1 GB/sec.
- WiFi module – dual band 2.4 GHz and 5 GHz, 802.11 b/g/n/ac, working with the drivers built in the latest system Raspbian / NOOBs
- Bluetooth 5 module is a popular wireless network in the newest 5.0 standard
- GPIO – 40 pin GPIO header used for LEDs, buttons, motor drivers and interfaces: I2C, SPI, and UART and many more.
