Two years ago, the Raspberry Pi was received at the beginning of the release, which was popular in the world's card computer accident, and became the hottest open source hardware platform. At present, the shipments of the Raspberry Pie have exceeded 3 million, and the computer to learn toys prepared for the children has become the favorite of the best.
Recently, the Raspberry Pie finally released an upgraded version of the Raspberry Party B +. Today, the upgraded version is really rare in two years. It is indeed less common. What kind of experience will the Raspberry Party B + bring to us?
Love board engineer got the latest Raspberry B + from European Electronics (RS), today we will see what it is upgraded?
Raspberry Part B +
If you use the Raspberry Party, especially friends who are spitted by the raspberry sport are disappointed. The main processor of the Raspberry Pista is not changed or 512MB memory and the BCM2835 processor packaged together.
We have compared that the size of the PCB size of B + has not changed, but it has a very big change in the function and layout (see below)
Raspberry Part B + VS Raspberry Part
USB2.0 interface increases to 4
As a card computer, a lot of peripherals (such as mice, keyboard, hard drive, wireless network card, etc.) are connected to the USB port. In general, we have to pick a USB hub because the two USB ports are not enough. Raspberry B + USB2.0 interface extends to 4, at least most people are used. The USB bridge chip on B + is upgraded from the LAN9512 to the LAN9514, which can support 4 USB2.0 interfaces and all the way USB to Ethernet bridge.

Changes in A / V interface
I believe many people "deep evil spirits" on the A / V interface on the Raspberry B, in this small card, should not be equipped with this interface. However, considering that the Raspberry Pist is initially as a learning tool for children, this RCA interface is also a "feature". On B +, it finally followed the trend. The more streamlined design is used. The A / V interface is designed to have a 4-pole 3.5mm composite video interface and moved to the same side of the HDMI interface, as shown below (next)
Raspberry Piece B + and B A / V Interface Design
The expansion interface is increased to 40pin
For the polar, the more and better the expansion interface. On the Raspberry Part B +, the change in the A / V interface also brought butterfly effects, and more onboard spaces have made the original 26PIN interface to 40PIN, which is more likely to develop DIY.

Change the microSD card interface interface
The oversized SD card interface is also a large slot point of the Raspberry Pie, on the back of the B + board, we have seen the microSD card interface returned by the expectations, as shown below
Raspberry Part B + MicroSD Card VS Raspberry Party B SD Card
Raspberry Part B + In addition to the most intuitive changes in the above 4 points, there is also a well-designed design in many details. like
Changes of power supply design, switching power supplies from linear power to higher efficiency
Remove the original electrolytic capacitance, all board electronic components
While adding USB interface, the layout of the USB interface holder is within the scope of the PCB board.
The onboard LED lamp is reduced by 5, where the network status LED is integrated into the RJ45 interface.
The audio circuit design uses a lower noise power supply design
B +'s PCB panel is rounded, and 4 positioning holes are designed
More detailed comparison of B + and B can refer to the table below
Raspberry Part B + VS Raspberry Part
What did you find from the total change of Raspberry B + Zero Zero?
First of all, unfortunately, the main processor of B + has not changed, and the POP package combination of BCM2835 + 512MB RAM is still adopted.
Second, B + is optimized in detail and function, what is this?
As the Raspberry Pie is hot in the global open source hardware market, all kinds of projects based on the Raspberry Pieces are endless, and we are not difficult to find that the Raspberry Party originally made to the educational purpose is gradually entering the commercialization. If we feel fine, the change in Raspberry Party from B to B + is that it is an upgrade, more like a packaging of commercialization, in B +, through a richer expansion function, more refined board design, making it based on Raspberry B + platform is easier to become developers developed into new products, new projects. This may be the most important purpose of the Raspberry B + release. For enthusiasts, Xiaobian is more expected to have a major upgrade in performance configuration.
Small knot
Regardless of the purpose of B + changes, it is worthy of we can enjoy more features through the same price, more refined and small Raspberry B +, why not! At present, B + has a price of 240RMB / 1 in the European electronics. It is interested that there must be no missed, and the online will release the Raspberry PI B + board.
