Unlock the full potential of your IoT and wearable projects with our ultra-compact ESP32-C3 development board.
Powered by a high-performance 32-bit RISC-V single-core processor running at up to 160 MHz, this board delivers robust computing power in a thumb-sized footprint (22.52x18mm), perfect for space-constrained applications.

Key Features:
Dual Connectivity: Supports both Wi-Fi (802.11b/g/n, 2.4GHz) and Bluetooth 5.0, enabling versatile communication in Station, SoftAP, or hybrid modes.
Ultra-Low Power: Achieves deep sleep power consumption as low as 43μA, extending battery life for portable devices.
Enhanced Security: Built-in hardware accelerators for AES-128/256, RSA, HMAC, and digital signatures ensure secure data transmission and boot.
Rich Interfaces: Includes 1x I2C, 1x SPI, 2x UART, 11x GPIO (PWM), and 4x ADC pins for flexible peripheral connections.
Ample Memory: Features 400KB SRAM, 384KB ROM, and 4MB flash for storing code and data efficiently.

Design & Usability:
Crafted with a single-sided surface mount design, the board is easy to integrate into your prototypes.
An onboard blue LED at GPIO8 aids in debugging.
For power, it supports 3.3V–6V external supply (via the 5V pin) or USB Type-C—use only one at a time to prevent damage. Note: Avoid short circuits during soldering to protect components.

Serial Port Flexibility:
Utilize the default USB serial port for direct PC connectivity via for Arduino IDE, or enable the UART serial by configuring pins 20 (TX) and 21 (RX) with a USB adapter (disable USB CDC On Boot in IDE).

Ideal for developers, hobbyists, and educators, this reliable board combines performance, security, and compactness to bring your innovative ideas to life.
