Schematic reconstruction
About the Schematic reconstruction PCB
Schematic reconstruction is an open source PCB design by eehubio, published on GitHub. It is a board, with 5 components from 5 distinct parts.
Other key parts include the NE555. By type, the board carries 2 resistors, 1 IC, 1 LED and 1 capacitor.

Schematic reconstruction: common questions
How many components are on the Schematic reconstruction?
5 components, from 5 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Schematic reconstruction design files?
From the eehubio/schematic-reconstruction repository on GitHub, which has the schematic, a netlist and the BOM; the links under Design files point to each one.
Can I use the Schematic reconstruction design in my own project?
The repository has no license, so all rights stay with eehubio. Use it as a reference, and ask the author before reusing the design.
