Electronics Toolbox v6.0.00
Peter HoAbout this app
Developer Description
Advanced electronics calculators, pinouts & resources
The ultimate mobile toolkit for electronics engineers, hobbyists, students, and professionals!
Packed with more advanced calculators, references, and resources than standard apps, it covers everything from basic circuit design to complex systems analysis—all in one offline, easy-to-use app.
Math Tools: Solve systems of simultaneous equations, matrix operations instantly – perfect for circuit analysis and design calculations.
SMD Marking Search: Quickly look up component part numbers from SMD markings to identify unknown surface-mount devices on PCBs.
Programming Language References: Get fast overviews and syntax highlights for popular languages like Python, C/C++, Rust,etc
TTL & CMOS Quick Search: Instantly access pinouts, characteristics, and specifications for classic TTL (74xx series) and CMOS (40xx series) integrated circuits.
Formula Quick Search: Find and apply essential circuit formulas in seconds – including 555 timer (astable/multistable), op-amp configurations, oscillators, filters, star-delta transformation, and many more.
Nodal Analysis Calculator: Automatically compute node voltages and branch currents for complex
Equivalent Circuit Calculator: Simplify circuits with Thevenin and Norton equivalent calculations

Electronics Toolbox users say on Google Play
Kind of ridiculous how much information you can have in one app, with easy navigation to find what you're thinking of without knowing the name.
It's a pretty informal app really my fave thing on it is the AI but there a couple things that could be added to make it even cooler like a laser diode driver and the Mw Nm of some driver laser diodes that write at whatever x speed
I am beginner.
Why anterner need pro version how make Nicolas Tesla coil conductor?
Nice one,easy to use and also advisable for everyone to use for better results.
