The Raspberry Pi 3 Model B+ is the latest product in the Raspberry Pi 3 range, boasting a 64-bit quad-core processor running at 1.4GHz, dual-band 2.4GHz and 5GHz wireless LAN, Bluetooth 4.2/BLE, faster Ethernet, and PoE capability via a separate PoE HAT.
The Raspberry Pi 3 B+ has four built-in USB ports that provide enough connectivity for a mouse, keyboard or anything else that you feel the RPi needs. But if you want to add even more, you can still use a USB hub. Keep in mind, it is recommended that you use a powered hub so as not to overtax the onboard voltage regulator. Powering the Raspberry Pi 3 B+ is easy just plug and Play with 5V/2.5A USB power supply into the micro USB port. There’s no power button, so the RPi will begin to boot as soon as power is applied. To turn it off, simply shut down the Pi 3 B+, then remove power. The four built-in USB ports can even output up to 1.2A, enabling you to connect more power-hungry USB devices.
