## Description

Your SMART reference for repairing chips, boards, and precision instruments. No internet? No problem. Everything is stored on your device – fast, private, and always available.

Why choose Device Fixer Handbook?

Complete chip database – Search by marking, model, package, or type. Get pinouts, electrical specs, typical failures, and application circuits instantly.

Visual pinout & package finder – Identify components by package type (DIP8, SOIC8, QFN, TQFP, BGA) or by pin count. See clear package images and pin assignments.

Built‑in electronic calculators – Resistor color code decoder, SMD resistor & capacitor calculator, voltage divider, Ohm’s law, power dissipation, zener diode and transistor substitution – all in one place.

Reference circuits & repair tips – Browse popular schematics (LM317, NE555, L298N, TOP223, UC3842, etc.). Tap any component on the schematic to see likely failure points.

Diagnostic checklists – Step‑by‑step guides with images: MOSFET testing, short‑circuit finding (voltage injection), BIOS flashing via CH341A, voltage regulator verification, and more.

Repair logbook – Fully local database to track devices, clients, dates, costs, photos (before/after), and notes. Search by model or keyword – all private.

Voltage reference library – USB 5V, logic 3.3V, CPU core 1.2V, DDR 1.35V – with symptoms and measurement methods.

Firmware library – Browse and export BIN, HEX, ROM files (EEPROM, BIOS, MCU) with built‑in search and info viewer.

Learning & glossary – Understand BGA, QFN, ESR, SMD, MOSFET, LDO. Decode SMD markings (e.g., 1A, A7, 6BW) and avoid common beginner mistakes.

User notes & bookmarks – Add personal notes to any chip or schematic. Keep your knowledge organized.
