Description
Digital toolbox for electronics engineers and electricians. Calculators and references for beginners and professionals — for work, study, DIY, and repair. Used by over 100,000 users. Completely ad-free.
Included tools:
• Datasheet search
• Equivalent parts search (cross reference for transistors, diodes and ICs)
• Resistor color and digit marking (4, 5 and 6 band color code; 2 symbols, 3/4 digit and EIA-96 code SMD resistors code)
• Electronic schematic symbols (IEC 60617, IEEE 315 and GOST standards)
• Pinouts of connectors and interfaces (USB, HDMI, DisplayPort, DVI, VGA, Thunderbolt, Apple Lightning and 30-pin, SATA, PCI Express and M.2, Ethernet RJ45 with PoE, RJ11/RJ14/RJ25, RS-232/422/485, IEEE 1394 FireWire, ATX, computer fans, SD card, audio jack, RCA, MIDI, XLR, PS/2, D-sub, SMEMA)
• Pinouts of boards and microcontrollers (Raspberry Pi and Pico, Arduino, ESP32, ESP8266, STM32 Nucleo, Teensy, Orange Pi, RADXA Rock Pi, LubanCat, Flipper Zero, ATmega and ATtiny)
• Ohm's law calculator
• AWG converter (wire diameter, cross-section area, resistance and maximum current)
• Resistor for LED
• Voltage divider
• Wheatstone bridge (output voltage or unknown resistance, current and power of every arm)
• Capacitor code
• Capacitor markings
• Capacitor ESR tables
• Frequency response curve calculation of passive filters (RC, RL, RLC, LC)
• Inductor color code

• Ideal transformer (winding turns, voltages and currents)
• Linear current regulator
• SMD packages list
• Reactance
• PCB trace resistance
• Active, apparent and reactive power
• RMS converter (peak, RMS and peak-to-peak values for seven waveform shapes)
• 555 waveform generator
• Operational amplifiers
• RLC circuit
• Number conversion
• Unit converter
• Cable voltage drop
• Battery life (runtime of a battery pack, with discharge curve)
• NTC thermistor resistance
• Logic gates

• Zener diode regulator (Zener diode and series resistor selection from a catalogue of 438 parts)
• Load cell (bridge output voltage to weight, force, pressure or torque)
• BJT voltage divider biasing
• Transformer turns per volt (from core area, flux density and frequency)
• Junction temperature (with or without a heatsink, power derating curve)
• Solar string dimensioning (minimum voltage and current ratings for a PV array)
• Solar cable and fuse selection (NEC and IEC rules)
• 555 astable generator with variable duty cycle
