Raspberry Pi 3 serial interface
On the board there are two so called serial interfaces. The first one is for a LCD display and the second one is for the official Raspberry Pi camera.
Apart from that, there is a chip from Broadcom on the board, a so-called System-on-a-Chip. A system-on-a-chip is a chip with all the necessary modules for a computer, such as the main processor, RAM, sound and graphics processor. All these modules are combined on this one chip.
The processor is 64-bit with four cores and operates at 1.4 gigahertz per core up to 70 degrees. Depending on the operating temperature, the clock rate is automatically set further down. Up to 80 degrees it is then only 1.2 gigahertz per processor core. Above 80 degrees, the clock rate automatically decreases further and further.
Working memory (RAM)
The working memory (RAM), which also sits on the SoC, is 1 gigabyte and the graphics processor works with 400 megahertz per second. Furthermore, an HDMI output is installed, which can render a resolution of 1080p in FullHD.
Composite audio & video connection
Furthermore, the Raspberry Pi 3B+ has a 3.5 millimeter audio port, which is also a composite video port. If you can't use the HDMI output, this is an alternative way to output the video signal via this video output.
Micro-USB power connector
40 PIN Connector
USB ports & network connection
Other than that, there is also a micro-SD card slot installed under the motherboard, which serves as hard drive storage. By the way, the Raspberry Pi 3B+ has a power consumption of about 3-5 watts under full load. That's roughly 7-8 Euros of electricity costs per year if it would run every day. So the operating costs are very low. So much for the technical data of the Raspberry Pi 3B+.
