1. Micro-USB Power Supply: A 5V micro USB typically powers the Raspberry Pi. But how much current (in milliamps or amps) the Pi requires to function depends on your usage.
The recommended amount is between 700mA for a Raspberry Pi Model A, and up to 2.5A for a Raspberry Pi 3 Model B.
The Raspberry Pi boards typically draw much lower amounts, between 200 and 500mA.
Usage depends on what you’re doing with the Pi. Playing video and browsing the web draws more power than idling and booting. It also depends on what devices you have connected; some keyboards and mice draw more power than others.
2. SD Card Slot: Secure Digital Card slot (SD Card) slot is a solid-state removable storage device which is required to run operating systems on Raspberry Pi as Raspberry Pi doesn’t have any onboard memory and data storage functionality. Raspberry Pi supports both SDHC (Secure Digital High Capacity) and SDXC (Secure Digital eXtended Capacity). The best suited card for proper running of all sorts of operating systems without any hiccup is Class 10 with speed @ 10MB/sec.
3. USB Ports & Ethernet Port:
USB Port: The number and type of USB ports on Raspberry Pi depends on the model. The Raspberry Pi Model B is equipped with two USB 2.0 ports; the B+, 2B, 3B and 3B+ have four USB 2.0 ports. The Pi 4 has two USB 2.0 ports and two USB 3.0 ports.
In all models prior to the Pi 4, the USB ports connect to a combo hub/Ethernet chip, which is itself a USB device connected to the single upstream USB port on BCM2835. On the Pi 4, the USB hub chip is connected to the SoC using a PCIe bus. On the Model A and Zero range, the single USB 2.0 port is directly wired to the SoC.
