The Raspberry 3 B+ is now official. One year after the last model, the foundation offers at the same price (around thirty euros) an overinflated version, 50% faster than the previous generation (Raspberry Pi 2 B), and whose SoC is slightly faster than on the Pi 3 B version. But also with WiFi ac dual-band, Bluetooth 4.2, and better power management with the arrival of Power-over-Ethernet.
For those who don’t know them yet, the Raspberry Pi are real Swiss Army Knives for all your do-it-yourselfprojects. These are actually small, extremely cheap computers. The long connector that you see in the top left corner is actually a set of “pins” called GPIOs. You can connect sensors, relays, LEDs… analog or digital, whatever you can think of! Since it is a small computer, you can install Linux on it and then check the operation of these ports, read values, and integrate all this into more complex programs. As the saying goes:sky is the limit.
Raspberry Pi 3 B+: what are the new features and differences with the Raspberry Pi 2 B and Raspberry Pi 3 B?
Of course many users will never use the GPIO ports, and will instead just install an OS and mediacenter application like Kodi. Because it is able to play HD videos and send them directly with the sound to your TV via its HDMI port. The new Raspberry Pi remains at the same price as version 2 but is nevertheless much more powerful and complete. It has a quad-core CPU at 1.4 GHz (64 bits) as opposed to 1.2 GHz (64 bits) on Pi 3 B, and 900 MHz on Pi 2 (32 bits). Finally, the new Pi’s have a chip to natively handle 802.11ac Wifi (3.5 GHz and 5 GHz), Bluetooth 4.2 and the card can be powered over-ethernet.
As far as ports are concerned, we stay on the same offer as the Raspberry Pi 3 B – with virtually the same placement (no need to buy new boxes): 4x USB 2.0, 1x full width HDMI, 1x quad audio + composite video jack, one microUSB power port, 1x Gigabit Ethernet (up to 100 Mb/s) with PoE support, 1x CSI to connect a camera, 1x DSI to connect a touch screen, and of course 1x GPIO 40 Pin. In addition, the B+ version brings the following new features:
- Improvements in power management (double step-down for 3.3V and 1.8V, reverse polarity protection on 5V, 2A fuse and protection for hot connections)
- Broadcom BCM2837B0 64-bit four-core ARM Cortex-A53 processor clocked at 1.4 GHz instead of 1.2 GHz
- Better management of heat dissipation
- New USB / Ethernet controller
- 40 GPIO pins instead of 26
The Raspberry Pi 2 B+ is available all over the world for between 30€ and 35€, for the moment only through two resellers authorized by the Pi Foundation:
