Ohmlattice: Bench Reference

Ohmlattice: Bench Reference is a private, offline electronics workbench for identifying components, solving circuit values, keeping your parts drawers in order and documenting your builds. NEW IN 2.0 - Save any calculator result, with its inputs and your note, into a project - Component inventory: values, packages, drawer locations, quantities and low-stock warnings - Stock check: compare a project's bill of materials with your inventory for any number of builds, then take the parts out of stock in one step - Favorite calculators and pinouts, plus recently used calculators - One search across calculators, pinouts, SMD codes, reference tables, your inventory, projects and saved calculations - Full backup and merge-safe restore of all your data as a single file - Project reports in Markdown with BOM and saved calculations; CSV and JSON exports BENCH-READY TOOLS - Identify resistor color bands with the camera or enter 4, 5 or 6 bands manually - Look up SMD markings with OCR-tolerant search across 2,650 codes, including EIA-96, EIA-198, 3- and 4-digit codes and common SOT-23 markings - Browse 127 vector pinouts for ICs, boards and connectors; tap any pin, search by pin name - 46 circuit and design calculators: Ohm's law, dividers, LED resistors, RC/RL/LC timing and filters with Bode plots, 555 timers, op-amps, regulators, batteries, IPC-2221 trace width, RF and sensors - Decode capacitor codes, resistor color codes and E-series values (E6 to E192) - Wire gauge table with diameters, resistance, NEC 310.16 ampacity and fusing current; voltage-drop calculator that suggests a gauge - Logic family levels and battery chemistry tables ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking or network access - Reference data and calculations work offline - Camera access is optional and used only for an identification action you start - Your work stays on the device unless you deliberately export it Engineering reference aid only. Confirm pinouts, limits, tolerances, thermal behavior and safety requirements against current component datasheets and applicable standards before building or servicing equipment.
