Raspberry Pi has revolutionized the single-board computer (SBC) market with its versatility and affordability, since it first launched in 2012. Today, the foundation refreshes the lineup with the new Raspberry Pi 4, bringing in more powerful hardware and features.
The whole computer is powered by a Broadcom BCM2711 SoC with four ARM Cortex A72 CPU cores inside, clocked at 1.5 GHz. For the first time ever, you can now choose to equip your new Pi with either 1 GB, 2 GB or 4 GB of LPDDR4 RAM. This should provide noticeable improvements over the existing Pi 3 Model B+.
The full-size HDMI port is replaced by two micro-HDMI ports, that can support two displays with resolutions up to 4K at 60 frames per second. Four USB ports stay the same, which two of them have upgraded to USB 3.0. For connectivity, the Raspberry Pi 4 has the same dual-band 802.11ac Wi-Fi. The Gigabit Ethernet port can run at its full 1 Gbps throughput with no limitation. Newer Bluetooth 5.0 is also onboard. You now need to power the computer using a USB Type-C port, instead of a micro-USB one.
The standard DSI/CSI display/camera ports and 40-pin GPIO header remain identical and fully backwards compatible with older boards. The base model with 1 GB of RAM costs the usual $35 USD (MSRP), while $45 USD for 2 GB RAM and $55 USD for 4 GB RAM. They should be available for purchase now on their approved sellers.
