Electronic Toolbox 2 – The classic, re‑imagined
Since 2009, Electronic Toolbox has been one of the most comprehensive electronics references and toolboxes on the App Store—for professionals, students, makers, HAMs, and hobby engineers.
With Electronic Toolbox 2, a fully modernized new edition arrives: familiar in structure, up to date technologically, and consistently evolved.
# The best and most complete electronics app—now for iPhone, iPad & Mac
Over 70 tools, tables, and references—from “A” like ASCII table to “Z” like Zener diode calculation:
Everything you need in the lab, workshop, or lecture hall, in one place.
• Universal app: One purchase—three platforms (iPhone, iPad, Mac)
• iCloud sync: All settings and favorites automatically on all devices
• Multi‑window support: Use multiple tools in parallel—ideal for comparisons
• PDF export: Save, document, or share results
• Pinned tools: Keep important tools always at hand
• Interactive tools: New visualizations, e.g., in the Battery Charge tool
• Modern UI with Dark Mode: Redesigned, clearly structured, and easy to read
# Proven foundation, familiar workflow
Electronic Toolbox 2 stays true to its heritage—all known tools are included and have been carefully revised.
From calculators to reference data: nothing is missing, much is better.
Examples:
• Resistor color code and coil calculator
• NE555 and heatsink calculation
• Conversion and unit tools (HEX, AWG, frequency, and more)
• Parametric component search with datasheets
• Tables for batteries, drill sizes, IC pinouts, packages, and more
• References for boards like Raspberry Pi, Arduino, BeagleBone, Nano Pi …
• Global search across all tools
• Fully usable offline
• No ads, no in‑app purchases
# Continuously improved—since 2009
Electronic Toolbox has been maintained and improved with passion for over a decade.
With version 2, we carry this legacy forward—on a new technical foundation for the years ahead.
Feedback from the community remains central: every suggestion helps make the toolbox even better.
# Gentle transition
The original Electronic‑Toolbox Pro remains fully usable—existing workflows are not interrupted.
Existing customers can switch to the new version via a discounted bundle.
Features like the Circuit Editor or Projects will initially remain exclusive to Electronic‑Toolbox Pro and are not yet included in this new edition.
# From the developer
Jan Roskosch built Electronic Toolbox 2 together with his father Marcus Roskosch, the developer of the original app.
A modern realization of a classic—with the same passion for electronics, precision, and quality.
# At a glance
• Completely new, modern interface
• All known tools from the original app included
• Universal app for iPhone, iPad, and Mac
• iCloud synchronization
• PDF export & multi‑window support

Electronic Toolbox 2—the future of the electronic toolbox.
Continued with passion. Built for you.
Hva er nytt i denne versjon? (1.3.1)
• Air coil calculation fixes - Fixed wire diameter scaling, DC resistance formula, and inductance unit conversion for accurate results.
• MC34063A tool improved - The DC-DC converter now shows detailed error messages with operating limits and validates peak current before discarding results.
• Karnaugh Map expression fix - Simplified expressions are no longer clipped and can be copied as plain text.
• Number converter fix - Decimal inputs now correctly produce float values with positive exponents.
• Color tool: RGB & HSL percentages - Added RGB and HSL percentage display formats for iCircuit compatibility. Fixed incorrect percent sign on H in the HSL system.
Thanks for your great support and feedback which helps to further improve this App.
