Blinky
About the Blinky PCB
Blinky is an open source PCB design by Sadrita404, published on GitHub under the MIT license. It is a 2-layer board measuring 70 × 70 mm, with 21 components from 12 distinct parts.
Other key parts include the NE555P, LM7805_TO220 and 4017. By type, the board carries 10 diodes, 3 ICs, 3 connectors, 2 capacitors and 2 resistors.
From the project
It is A 555 LED chaser board — a classic beginner PCB project.

For this Project I only need the grant of $14 for the PCB and for the other parts it will provided by Hack Club ( Blinky Board Kit) as it is already selected .
