Disclaimer

No warranty

The calculators, charts and pinout diagrams on hobbybench.site are provided free of charge, as they are, with no warranty of any kind. There is no promise that any result, table or diagram is complete, current, or fit for a particular purpose.

Check before you build

Electronics involves real energy. A calculator result is a starting point, not a substitute for checking the datasheet of the actual part in your hand. Board revisions differ, parts get counterfeited, and a pinout that is right for one module can be wrong for its sibling. Verify against the manufacturer's documentation before you connect power, and never rely on this site alone for anything involving mains voltage, batteries that can burn, or hardware you care about.

Not professional advice

Nothing here is engineering advice. The content describes general behavior of common components for hobby use. For work that must meet a code, a standard or a safety certification, hire someone qualified to sign off on it.

No liability

To the fullest extent permitted by law, hobbybench.site and its operator accept no liability for any loss or damage arising from use of this site, including damaged components, damaged equipment, injury, fire, or projects that do not work the way the math said they would.

Third parties

Product names such as Arduino, ESP32, Raspberry Pi and others identify the hardware the diagrams describe. Their trademarks belong to their respective owners, and this site is not affiliated with or endorsed by any of them. External links point to sites this one does not control.

Changes

The tools and this disclaimer can change at any time without notice. Continued use of the site means acceptance of the current version.
