Overview
The Raspberry Pi 3 Model B+ is a significant upgrade over its predecessors Pi 3 Model B, offering a faster 1.4GHz 64-bit quad-core processor and improved connectivity. It features dual-band wifi (2.4GHz and 5GHz), Bluetooth 4.2, and Gigabit Ethernet for seamless connection to various devices and networks.
Despite the performance boost, the Raspberry Pi 3 Model B+ maintains the same physical size of 85 x 56 mm as its earlier versions. It includes 1GB of memory and a Broadcom BCM2837B0 Cortex-A53 64-bit SoC for efficient processing. In terms of multimedia capabilities, it boasts a full-size HDMI port, 4x USB 2.0 ports, MIPI DSI display port, and MIPI CSI camera port.
