Raspberry Pi 3 B

There are two giant upgrades in the Pi 3. The first is a next generation Quad Core Broadcom BCM2837 64-bit ARMv8 processor, making the processor speed increase from 900 MHz on the Pi 2 to up to 1.2GHz on the Pi 3.

The second giant upgrade is the addition of a BCM43438 WiFi chip BUILT-IN to your Raspberry Pi. No more pesky WiFi adapters - this Pi is WiFi ready. There’s also Bluetooth Low Energy (BLE) on board making the Pi an excellent IoT solution (BLE support is still in the works, software-wise)

Lastly, there’s an upgraded switched power source that goes up to 2.5 Amps instead of just 2 Amps - allowing your Pi to power even more powerful devices over USB ports.

The best part about all this is that the Pi 3 keeps the same shape, connectors, and mounting holes as the Pi 2. The only difference is a slight change in where the LEDs are. 99% of cases and accessories will still be fully compatible with the Pi 3, Pi 2, and Pi B + - though if you have a case with a metal top there might be some WiFi chip difficulties.

Note: Our 5V 2.4 A power supply works great with the Pi 3 Model B and provides plenty of power to the chip, Ethernet, and any USB add-ons you plug in.

You'll also notice the metal heatsink on the CPU looks a lot like the one on the 3B+. In fact, it is the same CPU but downclocked from 1.4GHz to 1.2GHz!
