The Raspberry Pi 3: Model B vs. Model B+

The Raspberry Pi 3 comes in two different versions: Model B and Model B+. Below are the key differences between them:

Processor

Ethernet

WiFi

Power over Ethernet (PoE)

RAM

Ports

The B+ model also features a slightly faster revision of the Broadcom processor and improved networking hardware, including Gigabit Ethernet, PoE, and dual-band 802.11ac WiFi. The B+ model is designed to be compatible with the same cases and add-ons as the Model B, ensuring a smooth upgrade path. While the processor upgrade is modest and may not significantly impact performance for all use cases, the networking improvements make the B+ model more suitable for projects that require faster or more robust network connections.

PinOut

The 4 pins under the GPIO pins are only available on the Raspberry Pi 3B+ and are used for PoE.
