It centres on an ESP32 development board and a 0.96-inch OLED display, letting you create sensor dashboards, data loggers, and wireless control panels right out of the box. Beginners get a ready-to-use platform that combines powerful Wi‑Fi and Bluetooth with a crisp monochrome screen, making it easy to see sensor readings and network status while learning.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMicrocontroller\u003c\/td\u003e\n\u003ctd\u003eESP32-WROOM-32 dual-core 240 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWireless\u003c\/td\u003e\n\u003ctd\u003eWi-Fi 802.11 b\/g\/n, Bluetooth 4.2 and BLE\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003e0.96\" OLED 128×64 px, I2C (SSD1306)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e5V (USB) with 3.3V I\/O logic\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFlash Memory \/ RAM\u003c\/td\u003e\n\u003ctd\u003e4 MB Flash, 520 KB SRAM\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eIoT weather station showing live temperature and humidity on the OLED\u003c\/li\u003e\n  \u003cli\u003eWireless notification display that pulls tweets or emails from the web\u003c\/li\u003e\n  \u003cli\u003eBluetooth proximity tag that shows signal strength and device name\u003c\/li\u003e\n  \u003cli\u003eHome automation dashboard that toggles lights and reads sensor status\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis kit works with the Arduino IDE, MicroPython, and Espressif IDF. All I\/O is 3.3 V logic, so 5 V sensors like the HC-SR04 ultrasonic module need a simple level shifter. The OLED and included jumper wires connect directly to standard ESP32 development boards with 2.54 mm pin headers.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect the OLED SDA pin to GPIO21 and SCL to GPIO22 on most ESP32 boards. Power the display from the 3.3 V rail – avoid the 5 V pin to prevent damage. Always unplug USB before wiring, and keep current draw per pin below 12 mA.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
