Electronics Kit

Electronics Kit is a powerful utilities collection for hobbyists, electronics engineers, and professionals. It bundles calculators, pinouts, and reference resources to help design, test, and troubleshoot circuits. The app offers a free version (ads) and a PRO version with extra features and an ad-free experience.

A standout feature is the Component Value function for selecting component combinations to achieve a desired corner frequency, equivalent resistance, capacitance, and inductance, along with a wide range of calculators for series/parallel components, impedance, voltage dividers, RC/RL/LC filters, and more. It also provides extensive pinouts (HDMI, USB, Ethernet, etc.) and reference materials (SMD packages, resistor markings, logic gates, wiring tables), plus convenient sharing options to export CSVs via AirDrop or save to iCloud Drive.
