Logikz
About the Logikz PCB
Logikz is an open source PCB design by aroyx, published on GitHub. It is a 2-layer board measuring 93.2 × 85 mm, with 24 components from 5 distinct parts.
By type, the board carries 9 switches, 7 resistors, 6 transistors, 1 battery holder and 1 diode.
From the project
logic gates using npn transistors
I designed a simple circuit board that can function as three different logic gates:- AND, OR, and NOR
The first iteration would've never worked, because of absolutely no current calculations done. Used circuit.js to fix my implementation. Earlier it had like 5 buttons, two for A and B inputs and the rset for choosing between the gates. But had to ditch that idea because current it didn't work in the simulation. Now I have 9 buttons, A and B for each gates, so total 3 A and 3 B input buttons.

Logikz: common questions
How big is the Logikz PCB?
The Logikz measures 93.2 × 85 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Logikz?
24 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 Logikz design files?
From the aroyx/Logikz repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Logikz design in my own project?
The repository has no license, so all rights stay with aroyx. Use it as a reference, and ask the author before reusing the design.
