Raspberry Pi 4B - numerous connectors that fit your needs

The PCB of the latest Raspberry Pi model looks very similar to previous versions of this minicomputer, but the equipment and accessories have been significantly enriched. In turn, the unchanging elements are the microSD card slot and a 40-pin GPIO connector. For communication with a computer and other external devices, Raspberry Pi 4B uses two USB 2.0 connectors, as well as two USB 3.0 connectors with a bandwidth of 5Gb/s, which are great for sending large amounts of data. Support for video capture and display devices is provided by CSI and DSI connectors. Using these connectors, we can connect the dedicated camera and graphic display modules to the Raspberry Pi 4B. However, if you want to use the latest Raspberry Pi computer in the same way as with a regular PC, then using the aforementioned USB ports, you can equip it with a keyboard and mouse, and the image can be displayed on one or two LCD monitors that you can connect to the micro HDMI sockets. Do you want to listen to music or talk via Skype? There, you got it - a 3,5mm TRRS jack provides a left and right channel for an audio and single-channel for analog video transmission.

Raspberry Pi 4B - faster CPU, top quality graphics, adjustable software and built-in dual-band Wi-Fi

Another major change in the internal circuitry of the latest Raspberry Pi model is a new Broadcom BCM2711 quad-core processor based on an ARM Cortex A-72 architecture. Compared to BCM2837 chip used in the previous model - Pi 3B+, the clock speed has been raised from 1,4GHz to 1,5GHz. Besides the central processing unit, BCM2711 chip consists also a Video Core VI GPU with support for HD1080p/30FPS, 4K/60FPS, and OpenGL ES v1.1, v.2.0, and v3.0 standards. In Botland Store, Raspberry Pi 4B is available in three versions of RAM LPDDR4 memory - respectively 1GB, 2GB or 4GB. This single-board computer is running on a dedicated Raspbian Operating System but it supports other Linux-based systems and Windows 10 IoT Core too. The next great feature is that the wireless connection with external devices is implemented in two ways - with a Bluetooth Low Energy 5.0 module and dual-band Wi-Fi module that works typically at 2,4GHz or 5,0GHz. With those features, you can transform your Raspberry Pi 4B into a disk server, as well as the control panel of the alarm system receiving signals from cameras and motion sensors in a building placed miles away. The recommended output parameters of the power supply for the Raspberry Pi 4B minicomputer is 5VDC / 3A. Due to the type of power connector used on the PCB, the power supply cable must be a USB type C plug terminated.

Raspberry Pi 4B - cool and useful accessories

If you want to take full advantage of the huge capabilities of the Raspberry Pi 4B minicomputer, it is necessary to attach the appropriate equipment. The Botland Store offers dedicated enclosures, power supplies, cables, and memory cards. We especially recommend the dedicated Raspberry Pi 4B Desktop Kit, which in addition to the computer includes a mouse, keyboard, power supply, micro SD card with pre-loaded Raspbian OS files, HDMI cables, and user’s manual. We also offer starter kits containing necessary elements to do exercises from the original Raspberry Pi course, the content of which is freely available online on the FORBOT website.
