Description of product: Raspberry Pi 4 model B, Wi-Fi, 2x microHDMI, USB-C, USB 3.0, 4 GB of RAM 1.5 GHz
Raspberry Pi 4 model Bwith the increased RAM of 4 GB. This model has amore efficient processor, Broadcom BCM2711 quad-core 64-bitARM-8 Cortex-A72 1.5 GHz,two microHDMI ports,two USB 3.0 portsand 2 USB 2.0 ports, as well as a USB-Cpower supply connector. The board is supplied with dual-band 2.4 GHz and 5 GHzwi-fi, Bluetooth 5 / BLE, Ethernet port with speedto 1000 Mbpsand the possibility of power supply via PoE. The other characteristics remain the same as in model 3 B+. Onboard there are still: 40 pin GPIO header (2x20 pin, raster: 2.54), microSD slot for memory cards, DSI and CSI connectors, which allow for the extension with a camera and a display. Thanks to four mounting holes it is very easy to install the board in the chosen spot.
What is new in Raspberry Pi 4?
| Feature | Description |
|---|---|
|
3 versions of minicomputer |
Raspberry Pi 4 is sold in three versions, differing in RAM:
|
|
Processor BCM2711 |
Chipset Broadcom BCM2711 64-bit core Quad-core ARM-8 Cortex-A72 PROCESSOR, running at 1.5 GHz offers more power than the previous Raspberry Pi models. |
|
2 microHDMI display ports |
Raspberry Pi 4 has two microHDMI ports, making it possible to simultaneously connect two HDMI monitors with resolutions up to 4K(4K and 60 fps for a single display, and 4K and 30 fps for two displays). |
| 2 USB 3.0 ports | Minicomputer has 4 USB port. Two in 2.0 version and two powerful USB 3.0 ports. |
| Ethernet speed up to 1000 Mbps |
Ethernet connector in fullGigabit version, ethernet provides faster cable Internet. |
|
USB-C power connector |
The power connector has been adapted to modern standards. Raspberry Pi has a USB-C connector. The manufacturer recommends a supply voltage of 5 V / 3 A. |
|
Bluetooth 5.0 |
The new wireless standard, offering data transfer speeds up to 2 Mb/s. |
|
Layout of connectors |
The layout of the board remains the same, but the layout of the connectors has changed. |
Image and sound in minicomputer Raspberry Pi 4
Raspberry PihastwomicroHDMI ports, through which it can pass the image and sound even at 4 K and 60 fps for one display and 30 fps for twodisplays. Built-in 4-pin 3.5 mm Jack for headphones, speaker systems or for video output using standard RCA Composite. Raspberry Pi supports the compression standard H265 (4Kp60), H. 264 (1080p30)and graphicsOpenGL ES 1.1, 2.0 and 3.0.

Operating system for Raspberry
The drive of the minicomputer is stillthe microSD memory card. The manufacturer did not use memory eMMC. The operating system can be downloaded via the computer with the card reader. In our offer you will find a corresponging card with preinstalled software NOOBs that enablesyou to install one of systems: Raspbian, Openelec, RaspBMC, or OSMC Linux at the first run. There is also the possibility to install Windows 10 IoTindependently.

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 receiversevenin 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 Huballows 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 latestsystem 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.
