Feature Highlights: 1. Compatibility Note: Designed specifically for the 38-pin narrow version of the ESP32 module without mounting holes. Not compatible with other versions. 2. GPIO 1‑to‑2 Expansion: This breakout board expands one GPIO pin from your ESP32 development board into two separate pins. Perfect for smart home projects where you need to reuse every pin—great as a breadboard alternative too. 3. Two Connection Options: Choose between pin headers or screw terminals. Pick the one that fits your project best. 4. Double‑Layer PCB Design: Built as a stable two‑layer board with traces routed on both sides. This ensures reliable circuit performance, prevents poor contact, and delivers steady signal transmission—no more flickering or dropouts. 5. Ready to Use: The board comes fully assembled. No soldering required—just connect and go. Product Details: This ESP32 breakout board offers a simple way to expand GPIO access for your 38‑pin narrow ESP32/ESP32S module. It turns one GPIO into two, giving you extra flexibility in wiring smart home devices, sensors, or prototypes. The dual‑layer PCB keeps connections solid and signals clear, while the choice of pin headers or screw terminals makes wiring straightforward. Fully pre‑assembled for immediate use.
