Features: The module is safe, reliable, and scalable to various applications The expansion board adopts a double-layer design, with a pin on both sides Good stability and high reliability The breakout board can expand one GPI0 pin of the ESP32 board to two, great for you to reuse all the pins, and a great tool for your project A nice alternative to a breadboard is to extend one GPIO pin of the ESP32 board to two. Great for users to reuse all pins in DIY projects Specification: PCB material: high-quality FR-4 material Number of PCB layers: 2 layers PCB thickness: 1.6mm Size: 68mm*53mm*10mm Note: The expansion board is only suitable for the 30PIN narrow version of ESP32 without mounting holes. Please make sure your esp32 board pin width is the same as the expansion board pin width
