The module features a clearly labeled pinout printed on the top side, ensuring easy identification of all ESP-01 connections during prototyping. It fits perfectly onto a standard breadboard, making wiring far more organized and beginner-friendly.
To ensure stable operation, the adapter includes a 0.1 µF decoupling capacitor, which helps prevent voltage dips and keeps the ESP-01 running smoothly without unexpected resets.
Features
- Converts ESP-01 pinout to breadboard-friendly format
- Silk-printed pin labels for easy identification
- Includes 0.1µF decoupling capacitor for stable operation
- Fits standard breadboards
- Makes rapid prototyping with ESP-01 easier
