Generic Black ESP32 Breakout Board for 38-Pin Development

This breakout board is specifically designed for standard 38-pin ESP32 development boards. You should verify your board's pin header layout matches the common 38-pin footprint before purchase. It interfaces directly with the GPIO, power, and ground pins provided by these boards, serving as a passive expansion interface.

The board routes each signal from a single ESP32 GPIO pin to two separate physical pins on the breakout. This allows you to connect multiple components, like an LED and a button, to the same microcontroller pin or to branch a signal for testing without needing jumper wires. It effectively doubles the accessible connection points for each I/O line.

This breakout offers a permanent, organized, and mechanically stable connection point compared to a breadboard. It eliminates loose wires and unreliable breadboard contacts, providing a solid foundation for prototyping. It's ideal for creating semi-permanent test fixtures or for projects where you need reliable, repeated access to all ESP32 pins without soldering directly to the dev board.
