The Raspberry Foundation has launched the fourth version of the world’s favorite super-cheap and tiny computer. The Raspberry Pi 4 will be available for the same $35 price like its predecessors, but has some remarkable spec updates. The Raspberry Pi latest model has four times the RAM available in any of its previous versions, a faster CPU and GPU, faster Ethernet, dual-band Wi-Fi, and two USB ports.
The Raspberry Pi 4 continues the same design model – a single board with a lot of connectors. But everything else is different when it comes to the system. Its processor now uses Cortex-A72 architecture. This newest Raspberry Pi version has three RAM variants to choose from – 1 GB, 2GB, and 3 GB.
This one also has upgraded USB capacity. Along with two USB 2 ports, there are also two USB 3 ports, which can transfer data up to three times faster. Another USB update is the addition of a USB-C port for power supply. The Bluetooth 4.2 present in Raspberry 2 has been replaced by Bluetooth 5.0 in the Raspberry Pi 4.
The full-size HDMI port is gone and two micro HDMI ports have taken its place. The micro HDMI ports can power two 4K monitors at 30fps or a single 4K monitor at 60fps and another 1080p display monitor. This update features faster networking with Gigabet Ethernet along with onboard wireless networking, meaning that it no longer depends on a USB interface for network connection. The Operating temperature is 0 – 50 degrees C ambient. The 1GB, 2GB, and 4GB RAM variants of the Raspberry Pi latest model are available for $35, $45, and $55 respectively.
Raspberry Pi was created by Eben Upton to help schools impart computer education, today, it has become a versatile device used by educational institutes and businesses alike.
