ESP32 Smart IoT Learning Kit with OLED Display
ESP32 Smart IoT Learning Kit with OLED Display
The ESP32 Smart IoT Learning Kit is a complete starter pack for building Internet of Things projects with visual feedback. 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.

What You Can Build With This
- IoT weather station showing live temperature and humidity on the OLED
- Wireless notification display that pulls tweets or emails from the web
- Bluetooth proximity tag that shows signal strength and device name
- Home automation dashboard that toggles lights and reads sensor status
Compatibility
This 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.
Wiring Notes
Connect 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.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with the Arduino IDE?
Yes, the ESP32 can be programmed using the Arduino IDE. Install the ESP32 board package via Boards Manager and select the ESP32 Dev Module.
Does the kit include a battery pack?
No battery is included. The board is powered through the micro USB cable supplied in the kit. For portable use, you can connect a single-cell Li‑ion battery to the appropriate pins.
What other components can I connect to the OLED?
The OLED uses the I2C bus, so many sensors like the BME280, MPU6050, or an RTC can share the same SDA and SCL lines as long as each has a unique address.
📦 Free Setup Handoff Document Included
