Electronics toolbox pro

Electronics Toolbox Pro is an all-in-one electronics reference and calculator app for students, hobbyists, engineers, and circuit designers. Explore practical guides to components and ICs such as 555 timers, op-amps, BJTs, MOSFETs, diodes, capacitors, inductors, multiplexers, shift registers, Arduino Uno, ATmega328, and more.

Use a comprehensive suite of circuit design and analysis tools, including Ohm’s law, voltage divider, resistor and capacitor networks, resistor color and SMD code lookup, LED series resistor, voltage regulator, 555 timer, op-amp, transistor amplifier, and Q-point calculators. Design Butterworth, Chebyshev, Bessel, Sallen-Key, band-pass, and band-stop filters, or calculate RLC resonance, reactance, power, crossovers, attenuators, and PCB trace width. With a clean interface and fast results, the app helps users learn electronics, analyze circuits, and build projects more efficiently.
