Overview
LED Blinking PCB is an open-source printed circuit board by Trividha-ECE, from the Trividha-ECE/ECE-projects repository on GitHub. It is a 2-layer board of 31 × 27.5 mm with 8 parts on 8 nets, routed with 72 tracks and 0 vias.
It is built around the NE555P. Its parts include 3 resistors, 2 capacitors, 1 IC and 1 diode.

Project-2-LED-Blinking-NE555/README.mdNE555 LED Blinking Project
This project demonstrates a simple LED blinking circuit using the NE555 timer IC.
The repository includes schematic, PCB layout, 2D & 3D images, and Gerber files for PCB manufacturing.
Components Used
- NE555 Timer IC
- LED
- Resistors & Capacitors
- PCB layout designed in KiCad

Gerber Files
The folder LED_Blinking_Gerber_Final.zip contains all manufacturing-ready Gerber files.
How it Works
The NE555 timer is configured in astable mode, causing the LED to blink at a specific frequency.
You can modify the resistors and capacitor values to change the blinking rate.

Questions
How big is the LED Blinking PCB PCB?
It measures 31 × 27.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LED Blinking PCB use?
8 parts, built around the NE555P. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LED Blinking PCB KiCad files?
From the Trividha-ECE/ECE-projects repository on GitHub, at the commit this page was made from: the board is Project-2-LED-Blinking-NE555/LED_Blinking_PCB.kicad_pcb and its schematic Project-2-LED-Blinking-NE555/LED_Blinking_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED Blinking PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Trividha-ECE before reusing the design.
