There is no question that the Raspberry Pi 2 Model B is a step up from its predecessors. Before diving into what makes it such an incredible product, find out more about the family tree of Raspberry Pi products, starting with the oldest. It is as follows:
- Raspberry Pi B
- Raspberry Pi A
- Raspberry Pi B+
- Raspberry A+
- Raspberry Pi 2 Model B
The “+” versions were obvious upgrades to the previous versions, and the RPI2B is the direct descendent of the Raspberry Pi B+, with quite a bit of extra muscle. If you inquiring mind wants to know what makes this model so great, read on.
The 40 pin GPIO Header
The Raspberry Pi 2 Model B has the 40 pin GPIO header, just like the A+ and B+ models and the first 26 pins are exactly the same to the A and B models, which makes the new board the perfect drop-in upgrade for the majority of products. This newly designed board will also support all the expansion (HAT) boards that were used by previous models.
Video Output is Through a Full-Size HDMI Port
The video output that is offered by the Raspberry Pi 2 Model B is a full-sized HDMI port and has 14 HDMI resolutions ranging from 640 by 350 to 1920 by 1200 with digital audio. This board also offers composite video output for users.
Low-Noise Power Supply
Another thing the RPI2 Model B has in common with the B+ model is the audio circuit that has a dedicated low-noise power supply. This provides a higher audio quality, and the analog stereo audio is delivered on the four pole 3.5 mm jack that it is sharing with the composite video output.
The information here highlights the benefits offered by the Raspberry Pi 2 Model B and why it may be the best option for your project.
