Video, but too, in depth insights into the hardware features of the Raspberry Pi so Model B. In this video we will have a more in depth look into other hardware features of the Raspberry Pi four Model B like ports, networking chip controller chip connectors. First let's take a look at the USB type C power port, which is used to connect the Raspberry Pi to a power source. The USB type C port is a common sight on many mobile devices nowadays, you can use a mobile charger with five volts three amperes rating to power the Raspberry Pi for the presence of USB C port allows for more power delivery which allows for better overclocking capabilities. Many enthusiasts were able to overclock the pifo to about two gigahertz with proper cooling which is quite impressive Moreover, The USBC connector also supports OTG that allows you to connect the PI directly to your PC's USB port and access the device locally.

Please be aware that the current model of Raspberry Pi four has a design flaw due to a missing resistor does some USBC cables won't power the device. This happens if you use an emac USB cable. Usually, email cables are more expensive and come with larger, higher powered items like a USBC laptop. A normal Amazon basics USBC cable will work just fine. Since the pifo USBC port is wired incorrectly, these smart cables will detect the pifo as an audio adapter accessory and refuse to power them. If you want to know more about this issue, please check out the links in the resources small black chip can be found a little bit about the USB type C port.

This chip is known as a power management integrated circuit. And it handles the power that comes in the chip is from the MX l 7704 family. It is an all in one regulated chip that has features like high switching frequency, dynamic voltage scaling, fault protection, under voltage lockout, overcurrent protection and thermal protection. Now, let's have a deeper understanding of the networking chips in the Raspberry Pi four. We have a radio chip and an Ethernet controller chip on the Raspberry Pi for the Raspberry Pi four has the dual band aids zero to power 11 ac Wi Fi and throws in Bluetooth 5.0 support and improvement over the Bluetooth four on prior models. Most importantly, the Ethernet port now has more bandwidth, which allows it to offer a full gigabit of throughput.

Whereas prior models could only achieve about 330 megabits. The support for dual band Wi Fi means that you can now connect a faster five gigahertz Wi Fi access point. This will significantly reduce the latency for remote access and improve overall networking speed. Bluetooth connectivity is very important for IoT applications. The obvious advantage of Bluetooth 5.0 is its ability to transfer data at double speed and four times the distance as compared to Bluetooth 4.2. Bluetooth 5.0 also allows us to pair and communicate with multiple devices independently.

Bluetooth 5.0 can also replace Wi Fi implementation for small IoT edge devices in some applications. with Bluetooth Low Energy, due to its longer range and ability to communicate with multiple devices independently, the wired gigabit connection speed reaches well over 930 megabits per second in real life applications. This is especially useful for applications where we have to handle large quantities of data inside a LAN network of an office or a factory like in the case of network attached storage solutions. Next, we can take a look at the USB ports available for the Raspberry Pi four the PI for a fully featured USB Controller called via labs vl 805 drives the USB ports. It supports two USB 2.0 ports and two USB 3.0 ports. This is connected to the BCM 2711.

Soc through a PCI Link, which is extremely fast. This means that there is no bottleneck, and the USB poles can work at their rated throughput speeds. This is one of the biggest features of the Raspberry Pi four in terms of performance, because we have seen well over speeds of 340 megabytes per second with a solid state drive on the USB 3.0 port. This also means that we can connect USB 3.0 compatible devices directly to Raspberry Pi four. For example, we can connect the Google coral USB machine learning accelerator to the USB 3.0 to get double the performance of its USB 2.0 counterpart just behind the USB 2.0 ports. At the bottom edge.

You can see a headphone jack. It's actually a 3.4 millimeter audio visual jack. It's usually used as a headphone jack use to connect to amplified speakers. It also has a trick up its sleeve. This jack can output radio signal, which can be connected to TVs, projectors, and any displays that support a composite video input with a tr RS adapter. So technically speaking, the Raspberry Pi four has three video outputs and not just two.

Next comes the camera connector, which is also known as the camera serial interface, which allows you to connect and use the Raspberry Pi camera module. The CSA code is based on the mobile industry processor interface standards. Thus, you can connect any conventional mobile camera modules with a proper adapter. You might be wondering why to use CSS code for the camera. While we can use a high resolution USB camera, the CSI port uses An industry grid interface technology that supports up to four gigabits throughput does allows for high quality interfacing cameras. Moreover, it's directly interfaced to the GPU.

Thus, there is minimal load on the CPU. If we use a USB webcam, the CPU will be on constant pressure due to encoding and the frame rate will be considerably low. Thus, for computer vision applications, it's highly recommended to use the CSI port instead of the USB webcam. If you have no other choice than to use a USB webcam, please use a webcam with hardware encoding inbuilt and connected to USB 3.0 instead of USB 2.0 just left of the CSF hold. You can see that there are two macro High Definition multimedia interface boats This means that you can connect two displays at the same time. For a multi monitor setup.

All previous Raspberry Pi models had a single HDMI port. In pifo, they were able to cram two display ports in the space of one big HDMI port. The only problem is that micro HDMI connectors have not become as prevalent as HDMI connectors. So you may have to use an adapter if you don't have one. The two micro HDMI connectors enable Raspberry Pi for to drive to 4k displays at up to 30 frames per second, or a single 4k display at up to 60 frames per second. The native support for dual displays with 4k on a single board brings out many different applications for the Raspberry Pi for like in banks, factories, cashier machines, advertisement passes etc.

The final port we will take a look at is the display interface port, which is at the left extreme edge of the board. This port is similar to the camera port, but is used to interface external display modules. It's made with mobile interface standards, just like the CSI port, so that for applications that are very CPU intensive, the driving of the display is offloaded to the GPU, thus freeing up to the CPU summary. In this video, we have covered the following topics, ports, networking chip controller chip connectors. In the next video, we will take a look at essential accessories for the Raspberry Pi four and set up the hardware
