Last November the refreshed Raspberry Pi 3 Model A+ developer board landed on the market with a price tag of $25. A new version of the developer board has debuted called the Raspberry Pi 4 starting at $35. The Raspberry Pi 4 brings with it improved performance and more connectivity along withdual Micro HDMI ports supporting up to two 4K displays.
Raspberry Pi 4 is powered by a Broadcom BCM2711 quad-core Cortex-A72 64-bit unit running at 1.5GHz. The Pi 4 can be fitted with 1GB, 2GB, or 4GB of LPDDR4-2400 SDRAM. Both 2.4GHz and 5.0GHz 802.11ac WiFi is supported along with Bluetooth 5.0 BLE.
Wired connectivity support includes a gigabit Ethernet port, and the board has a pair of USB 3.0 ports and a pair of USB 2.0 ports. Raspberry Pi 4 features a 2-lane MIPI DSI display port, 2-lane MIPI CSI camera port, and 4-pole stereo audio and composite video port. A microSD card slot is integrated for OS and data storage.
Both 5V DC via USB-C connector with a minimum of 3A and a 5V DC via GPIO header with minimum 3A are built-in. Raspberry Pi 4 is compatible with Power over Ethernet (PoE) with a separate PoE HAT. Raspberry Pi 4 will sell for $35 for the 1GB version, $45 for the 2GB version, and $55 for the 4GB version. All versions of the board released today, but as of writing, they are listed as out of stock on Pieshop.us. Those wanting something along the lines of a Raspberry Pi, but needing something a bit cheaper can check out the Orange Pi 3 that launched in January. An even smaller and cheaper alternative would be the $10 Rock Pi S that will launch the summer.
