Electronics Reference

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.
