ElectroMate is an offline electronics workbench for technicians, students, repair professionals and makers. Calculate circuit values, identify resistor bands, decode component markings, check pinouts and follow practical troubleshooting steps from one bilingual app.
ELECTRONICS CALCULATORS
Use 15 practical calculators for common workshop and learning tasks:
• Ohm's law and electrical power
• Series and parallel resistors
• Voltage dividers
• LED resistor sizing
• BJT base resistors
• Battery pack capacity and estimated runtime
• BMS current sizing
• Buck and boost converters
• Operational amplifier gain
• RC cutoff frequency and time constant
• 555 astable timers
• Wire voltage drop
• Speaker impedance
• ADC voltage dividers
• Three-phase power
RESISTOR TOOLS
Choose four, five or six resistor color bands to calculate resistance, tolerance, minimum and maximum values, temperature coefficient when available, and the nearest E24 value. You can also select or capture a resistor image, tap each color band and let ElectroMate match the sampled colors to a calculated value. Results can be saved to your local history.
COMPONENT CODE DECODING
Enter the marking printed on a component to decode supported SMD resistor, capacitor and inductor codes, including common EIA-96 resistor codes.
OFFLINE COMPONENT AND BOARD LIBRARY
Browse and search 28 electronic component guides and 26 board or module references. Entries include practical descriptions, pins or pinouts, testing methods, common failures and replacement guidance. Save frequently used entries as favorites.
GUIDED TROUBLESHOOTING
Start with a symptom and follow ordered measurement steps instead of replacing parts at random. Review the built-in safety checklist before measuring circuits or applying power.
PROJECT WORKSPACE
Create local electronics projects with the project name, board, power supply, notes and a bill of materials. Edit or delete projects whenever needed.
BUILT FOR THE WORKBENCH
• Works offline after installation
• Arabic and English interface
• Light and dark themes
• No account required
• Projects, favorites, checklist progress and calculation history are stored locally on your device
ElectroMate is a reference and calculation aid. Verify calculations, component ratings, datasheets and safety requirements before building, repairing or powering a circuit. Do not work on mains voltage or high-energy batteries without suitable training, isolation and protective equipment.
