Raspberry Pi 3 B+ Overview:
Everyone knows and loves the Raspberry Pi, but what if the wireless capabilities only got better?
The Raspberry Pi 3 B+ is here to provide you with the same Pi as before, but now with gigabit and
PoE capable Ethernet, as well as better overheating protection for the 64-bit processor. The
credit-card-sized computer is capable of many of the things your desktop PC does, like spreadsheets,
word processing, and playing high-definition video and games. It can run several flavors of Linux
(and even Windows 10 free-of-charge) and is being used to teach kids all over the world how to
program... Oh yeah, and it does all that for about $40.
The secret sauce that makes this computer so small and powerful is the Broadcom BCM2837, an ARM
Cortex-A53 64-bit Quad Core Processor System-on-Chip operating at 1.4GHz. The GPU provides OpenGL ES
2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode. It is capable of 1Gpixel/s,
1.5Gtexel/s, or 24 GFLOPs of general-purpose compute. What does that all mean? It means that if you
plug the Raspberry Pi 3 B+ into your HDTV, you could watch Blu-ray quality video, using H.264 at
40MBits/s.
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 any 5V/2.5A USB
power supply into the microUSB 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.
On top of all that, the low-level peripherals on the RPi make it great for hardware hacking. The
0.1" spaced 40-pin GPIO header on the RPi gives you access to 27 GPIO, UART, I2C, SPI, as well as
3.3 and 5V sources. Each pin on the GPIO header is identical to its predecessor, the Model 3. If you
are planning to run a NOOBS card with the RPi3 B+ make sure that it is up to date with the latest
version!
