The ESP32-C3-OLED Mini Board is a compact, high-performance IoT development board designed for embedded systems, smart devices, and wireless applications. Powered by the Espressif ESP32-C3 single-core 32-bit RISC-V processor running at up to 160 MHz, it delivers reliable performance while maintaining low power consumption. The ESP32-C3 integrates 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5.0 Low Energy (BLE), making it ideal for IoT, home automation, wireless sensor networks, and portable electronics.

The board features a vibrant 1.42-inch OLED display, allowing developers to display sensor readings, system status, menus, animations, QR codes, and other graphical information without requiring an external screen. The integrated display simplifies prototyping and makes the board suitable for handheld devices, smart controllers, and monitoring applications.

A USB Type-C connector provides convenient power, programming, and serial communication, eliminating the need for external USB-to-serial adapters. With multiple GPIO pins supporting UART, SPI, I2C, PWM, ADC, and interrupts, the board can interface with a wide variety of sensors, actuators, displays, and communication modules.

Its ultra-compact design makes it perfect for projects where space is limited while still offering excellent wireless performance and flexible expansion.
