Raspberry pi led is a minicomputer

Raspberry Pi is a minicomputer meant to control and monitor the outside world. It is what physical computing has to offer to the world. Python programming is the backbone of these devices thus they are able to interpret their environments well. One of the Raspberry Pi’s powerful features is the GPIO pins line along the board’s top edge. GPIO stands for General-Purpose Input/Output. Such pins are a direct interface from the Raspberry Pi to the outside world. The Pi can power LEDs and turn them on or off.

The Raspberry Pi LEDs come in different models. This is as a result of the dynamic technology and the need to solve problems of different kinds, more desire for device performance and speed. According to their led these are the main models

Raspberry Pi 3

General specs are;

• Broadcom BCM2837 64bit ARMv7 Quad Core Processor powered Single Board Computer running at 1.2GHz
• Micro SD port for loading your operating system and storing data
• 1GB RAM
• port for connecting the Raspberry Pi touch screen display
• BCM43143 Wi-Fi on board
• Bluetooth Low Energy (BLE) on board 40pin extended GPIO
• 4 pole Stereo output and Composite video port
• Full-size HDMI
• CSI camera port for connecting the Raspberry Pi camera DSI display
• Upgraded switched Micro USB power source.
• Expected to have the same form factor as the Pi 2 Model B, however the LEDs will change position
• 4 x USB 2 ports

Raspberry Pi 2

This model came after the B+ Model. This means higher speed and better performance.it is six times faster than the previous model(B+ Model).

features

• CPU: Broadcom BCM2836 900MHz quad-core ARM Cortex-A7 processor
• USB Ports: 4 USB 2.0 ports
• RAM: 1 GB SDRAM
• Power Source: 5V Micro USB
• Weight: 45 g
• Network: 10/100 Mbit/s Ethernet)
• Power Ratings: 600 mA (3.0 W)
• Size: 85.60 mm × 56.5 mm

Raspberry pi zero

This is a model intended to give optimized results. There are two versions ;

• Raspberry zero W
• Raspberry WH

The two exhibit the following similar characteristics;

• 1GHz, Single-core CPU
• 512MB RAM
• Mini HDMI and USB On-The-Go ports
• Micro USB power
• HAT-compatible 40-pin header
• Composite video and reset headers
• CSI camera connector
• 802.11n wireless LAN
• Bluetooth 4.0

Status

The raspberry pi as well as different statuses. This is due to the result of the configurations on each.

• ACT/OK- It is normally green and implies the activity of the SD card.
• PWR – Red for power
• FDX – Green in color. Full-duplex LAN connected.
• LNK- Green for link/activity LAN
• 10M/100-Yellow 100Mbit (LAN) connected

Power

The red power LEDs display an active power supply for the Pi. The LED is connected directly to the 3.3V supply in Model A and Model B (rev 1). If it does not light or flashes, this means that the power supply is having a problem. The power LED is slightly smarter in the later models (A+, B+, Pi 2 & Pi 3). It attaches to the 5V and flashes when the voltage falls below.
