Description
The ESP32-C3 OLED Development Board is a feature-rich platform centered on the Espressif ESP32-C3FN4/FH4 chip, a single-core 32-bit RISC-V microcontroller capable of 160 MHz. It combines 4MB of internal flash memory with full 2.4GHz Wi-Fi 802.11 b/g/n and Bluetooth 5.0 Low Energy (BLE) support, enabling a wide range of wireless IoT applications from sensor nodes to smart home controllers. The integrated 0.42-inch OLED screen provides immediate visual output for debugging or user interaction.
Power management is handled via the USB-C port, which also serves as the serial programming interface. The board’s compact footprint and onboard ceramic antenna make it suitable for space-constrained and wearable designs. Its extensive peripheral set, including multiple ADC channels, I2C, SPI, and UART, allows for seamless integration with sensors, actuators, and other modules, accelerating prototype development for makers and engineers.
