An interactive ESP32 pinout for four boards, alongside five free electronics calculators for common project decisions.

Landing page captured for the 2026-10-14 issue.
For
ESP32 hobbyists and electronics builders
Worth noticing
The LED resistor tool gives an E24 value and power rating; the trace-width calculator covers IPC-2221 internal and external layers.

Field notes

The calculators translate circuit inputs into purchasing or design outputs: the resistor tool includes a nearest E24 value and power rating, while the trace tool can report resistance and voltage drop when length is supplied. The page says its pin data comes from Espressif user-guide tables and links sources from pin details. Coverage is limited to the four named boards; the site says it does not yet include every clone board.
