Description:Raspberry Pi 4 model B WiFi 2x microHDMI, USB C, USB 3.0, 8GB RAM 1.8GHz
Raspberry Pi in 4B version with 8 GB of built-in RAM! The minicomputer has a powerful Broadcom BCM2711 quad-core 64-bit ARM-8 Cortex-A72 1.8 GHz processor, two microHDMI connectors, two USB 3.0 and 2 USB 2.0 connectors and a USB C power connector. Similarly to other versions of RPi 4, it has dual band 2.4 GHz and 5 GHz WiFi, Bluetooth 5 / BLE, Ethernet port with speed up to 1000 Mbps and PoE power supply. Other features have not changed compared to the 3 B+ model. On the board you will still find 40 GPIO connectors, a CSI and DSI connector and a memory card slot (microSD). The 4 holes allow for easy installation.
The film presents the capabilities of the latest Raspberry Pi 4B minicomputer.
What's new in Raspberry Pi 4?
| Feature | Description |
|---|---|
|
3 minicomputer versions |
Raspberry Pi 4 is sold in three versions with different amount of RAM: |
|
BCM2711 processor |
Broadcom BCM2711 Chipset with 64-bit Quad-core ARM-8 Cortex-A72 CPU, 1.8 GHz clocked, delivers more processing power than previous Raspberry Pi models. |
|
2 microHDMI monitor connectors |
Raspberry Pi 4 is equipped with two microHDMI sockets, which makes it possible to connect two HDMI monitors up to 4K resolution (4K and 60 fps for one monitor and 4K and 30 fps for two monitors) simultaneously. |
|
2 USB 3.0 connectors |
The minicomputer has 4 USB connectors. Two in version 2.0 and two powerful USB 3.0 connectors. |
|
Ethernet speed up to 1000 Mbit/s |
Full Gigabit Ethernet connection for faster cable internet. |
|
USB C power connector |
The power connector has been adapted to the latest standards. Raspberry has a USB C connector. The manufacturer recommends 5 V / 3 A power supply. |
|
Bluetooth 5.0 |
New standard of wireless communication offering transmission speed up to 2 Mb/s. |
|
Connector layout |
The contour of the board remains the same, but the distribution of joints has changed. |
Image and sound in the Raspberry Pi 4 minicomputer
Raspberry Pi is equipped with two micro-sized HDMI connectors which enable video and audio transmission up to 4 K and 60 fps for one monitor and 30 fps for two monitors. A 4-field 3.5 mm jack socket is installed to connect headphones, speakers or analogue video via RCA Composite standard. Raspberry supports H265 (4Kp60), H.264 (1080p30) compression standard and OpenGL ES 1.1, 2.0 and 3.0 graphics.

Operating system for Raspberry
The raspberry drive, as before, is a microSD memory card. The manufacturer has not used eMMC memory. The operating system can be loaded using a computer with a card reader. In our offer you will find appropriate cards with installed NOOBs program, which on the first run gives the possibility to install one of the systems: Raspberry Pi OS, Openelec, RaspBMC, OSMC Linux.

Communication in Raspberry Pi 4
Raspberry Pi 4 has popular communication interfaces, available on traditional desktop and laptop computers. The most important of them are:
- 2 microHDMI connectors to simultaneously connect two monitors up to 4K.
- WiFi module - a 2.4 GHz and 5 GHz 802.11b/g/n/ac dual-band module - working with drivers in the latest Raspbian / NOOBs system.
- Bluetooth 5 module - popular 5.0 standard wireless connectivity
- 2 USB 3.0 and 2 USB 2.0 connectors to connect peripheral devices. USB 3.0 allows for quick transfer from an external drive. If there are not enough connectors - we recommend using a USB HUB.
- An Ethernet socket, which allows wired connection to the network at up to 1 Gb/s.
- GPIO - 40 general purpose output/input pins, used for LEDs, buttons, motor controllers and interfaces: I2C, SPI and UART interfaces.
Power supply for Raspberry in version 4 minicomputer
Raspberry Pi 4 needs a power supply with a USB C connector and an output voltage of 5 V. The minimum recommended current capacity is 3 A. Our offer includes original power supplies and branded replacements that work with Raspberry Pi.
