Terms of Use

By using ESP32 Calcs you agree to these terms. The plain-language summary: use the tools freely, expect the math to be right but verify anything important, and don't hold us liable for a smoked module.

The tools

• Calculators implement standard formulas (Ohm's law, IPC-2221, duty-cycle battery math) and are provided as-is, for reference.
• Pin data is transcribed from Espressif's official user guides but is not an official reference — always verify against the module's datasheet and your board's silkscreen.
• Nothing on this site is engineering assurance for safety-critical or commercial hardware.

Liability

To the maximum extent permitted by law, ESP32 Calcs provides the site "as is" without warranties of any kind, and shall not be liable for any damages arising from use of the calculators, pin data or guides — including damaged hardware, incorrect wiring, or decisions based on our numbers.

Trademarks

ESP32 is a trademark of Espressif Systems; Arduino and Raspberry Pi are trademarks of their respective owners. This site is independent and not affiliated with, sponsored by or endorsed by Espressif, Arduino or the Raspberry Pi Foundation.
