Electronics Reference

About this app

Electronics Component Reference is a beautifully crafted reference app for anyone who works with electronic components - from hobbyists building their first circuit to engineers at the bench. WHAT'S INSIDE • Resistors - Interactive color band calculator with common values and a visual guide to reading 4, 5, and 6-band resistors. • Capacitors - Decode ceramic capacitor markings, explore types, and look up values instantly. • Semiconductors - Reference cards for popular transistors and diodes, with a guide to PN junctions, BJTs, MOSFETs, and more. • Integrated Circuits - Browse a library of common ICs and the complete 74-series logic family, with pinouts and a family comparison guide (HC, LS, AC, LVC). • Microcontrollers - Specs and details for popular chips across ARM, AVR, and Xtensa architectures. • Boards - Pinout diagrams and GPIO references for Raspberry Pi 5 & 4, Pico, Arduino Uno & Nano, and ESP32. • Identify - Point your camera at a component and use OCR to identify ICs, capacitors, and microcontrollers from their markings. • Learn - Interactive common circuits, so you can always have the correct component values. Information on chip families, capacitor types and more., No ads, no account required, no internet needed.

• IC search now recognizes real markings such as  74HC00 ,  SN74LS04 ,  MC74HC00 , and package suffixes. • Identification results now open the relevant IC, MCU, logic, or capacitor reference. • OCR now respects image orientation and displays recognition failures instead of silently reporting no text. • Detected capacitor values show equivalent pF, nF, µF, and common markings. • Capacitor destinations avoid showing a misleading empty table when the conversion itself is the answer. • The home animation becomes static for Reduce Motion and while the app is inactive.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
