Electro Bench: SMD & Pinouts

Electro Bench is the pocket reference for electronics repair. Read the tiny code on an SMD part, see its pinout, and work out values without leaving the bench.

IDENTIFY SMD CODES
• Type the marking, or scan it with the camera
• See the part number, type, package and pin layout
• Save parts you look up often and find them again in your history

600+ PINOUTS, ONE SEARCH
• Transistors, MOSFETs, regulators, op-amps, timers, optocouplers and drivers
• 74-series (LS, HC, HCT) and 4000-series CMOS logic
• Every pin explained in plain language, drawn the way you hold the part
• Logic pinouts checked against manufacturers' datasheets

21 BENCH TOOLS
• Resistor colour bands and SMD codes, both ways
• Capacitor, inductor, potentiometer, varistor, NTC, crystal and fuse markings
• Ohm's law, LED resistor, voltage divider, zener regulator
• LM317 / TL431 regulator resistors, 555 timer, RC filter, op-amp gain
• Standard-value finder, capacitor discharge, heatsink, wire and PCB trace, battery life

REPAIR NOTEBOOK
• Keep a note for each repair: device, fault, parts checked and parts replaced
• Add parts straight from a search, with their board location
• Share a job or a pinout as a clean image

Made for repair technicians, students and hobbyists. Light and dark themes. Everything you look up stays on your phone.
