Raspberry Pi

Raspberry Pi has been one of the small series single board computer we have been using at City Tech in a number of research projects, classwork and etc. Whether it’s small project or a smaller part in a larger project, it has been considered one of the main components.


Hardware: The Raspberry Pi hardware has evolved through several versions that feature variations in memoryĀ capacity and peripheral-device support.

This block diagram describes ModelĀ B and B+; ModelĀ A, A+, and the PiĀ Zero are similar, but lack theĀ EthernetĀ andĀ USBĀ hub components. The Ethernet adapter is internally connected to an additional USB port. In ModelĀ A, A+, and the PiĀ Zero, the USB port is connected directly to theĀ system on a chipĀ (SoC). On the PiĀ 1 ModelĀ B+ and later models the USB/Ethernet chip contains a five-port USB hub, of which four ports are available, while the PiĀ 1 ModelĀ B only provides two. On the PiĀ Zero, the USB port is also connected directly to the SoC, but it uses aĀ micro USBĀ (OTG) port.

Specs: 1.4GHz 64-bit quad-core processor, dual-band wireless LAN, Bluetooth 4.2/BLE, faster Ethernet, and Power-over-Ethernet support (with separate PoE HAT).
