OSOYOO Breakout Board for 30-Pin ESP32 ESP8266 - Extension Adapter for ESP32 ESP8266 Modules with 30P Header - Easy Prototyping & Development - Ideal for IoT, Arduino, STEM & DIY Projects
The OSOYOO IO Breakout Board for 30-pin ESP32 and ESP8266 is a powerful, feature-rich expansion board for developers, educators, and electronics hobbyists working with ESP32 or ESP8266 modules. Compatible with most 30-pin ESP32/ESP8266 boards (including 0.9", 1" and 1.1" pin spacing), this breakout board provides a clean, reliable platform for prototyping, debugging and powering IoT projects. Each GPIO pin is paired with a status LED, making real- time debugging easier - no need for external cables or test equipment. These LEDs are powered independently to avoid interference with GPIO functions. The board includes dual power supply options: 5V/2A and 3.3V/500mA, with automatic USB/external power switching. Choose between 3.3V or 5V via the V_Selector Jumper to match your connected devices and avoid accidental damage with built- in reverse polarity protection. Power your board via USB, DC socket or screw terminals - providing flexibility for any setup. Connectivity is seamless with standard 2.54mm headers and 3-pin sensor/servo ports (V/GND/S) to ensure easy integration of sensors, LEDs, motors or other peripherals. A built-in power switch provides convenience, while a compact 88 x 60 mm design saves space in crowded work areas. Whether you are teaching STEM, building smart devices, or designing advanced control systems, this breakout board will make your development smoother, safer and smarter.
