Raspberry Pi 4B Computer
Overview
Release date:June 24, 2019
Picture of Pi 4B
Key Features
a high-performance 64-bit quad-core processor
dual-display support at resolutions up to 4K via a pair of micro-HDMI ports,
hardware video decode at up to 4Kp60
up to 4GB of RAM
dual-band 2.4/5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, and PoE capability (via a separate PoE HAT add-on)
Target Applications: Raspberry Pi 4 set to drive low-cost digital transformation
Next generation of best-selling British PC will dramatically cut the cost of digitally transforming business processes, products and services
Bringing PC-equivalent performance to the sub-$50 price bracket, Raspberry Pi 4 is the natural choice for developing and deploying industrial IoT applications
New 4K dual-screen capability increases the tiny computer’s suitability for thin client installations, where two monitors are often needed
Gigabit Ethernet, wireless networking and enhanced serial interfaces support networked monitoring and control of a broad range of industrial equipment
