## Description

ChipRef is a handy Chrome extension designed for electronics enthusiasts and developers. It provides quick access to pinouts and characteristics of widely used integrated circuits (ICs), including popular ATmega series chips like ATMega128 and ATMega328 used in Arduino, as well as ATTiny series chips like ATTiny85 used in Trinket devices. 

The extension stores pinout information internally for offline use, requiring internet access only when fetching detailed PDF datasheets via external links. ChipRef streamlines circuit design and debugging by offering essential IC references directly within your browser.

## Review summary

Users appreciate ChipRef as a handy and quick reference app, praising its usefulness and ease of avoiding external searches for chip pinouts. However, multiple reviews highlight its limited database with many chips missing, poor visualization of chip pins particularly on Android 10, and inadequate definitions of inputs/outputs. Requests for inclusion of popular chips like 8051 and Atmega328 are common.

### Pros

- Provides a handy and quick reference for chip pinouts
- Users find it excellent and among the best apps on the Play Store
- Helps avoid searching for different IC pinouts elsewhere

### Cons

- Lacks many chips and has a small database
- Poor display or missing information for chip pins, especially on newer Android versions
- Inputs and outputs on chips are poorly defined or presented
- Missing popular chip references like 8051 and Atmega328
