Additional Information
The ESP32-C3 Super Mini is an ultra-compact, high-performance, and cost-effective development board based on the powerful Espressif ESP32-C3 chip. This board features a 32-bit RISC-V single-core CPU running at up to 160 MHz, providing a strong balance of processing power and low energy consumption. With built-in WiFi + Bluetooth, it’s perfect for IoT projects that need reliable wireless connectivity.
The board offers flexible power management, supporting a wide input range of 3.3V to 6V. It can be powered via the onboard USB Type-C connector or an external power source, though users must select only one power input at a time.
Built with an ultra-compact form factor, this module fits perfectly into tight or space-limited projects. Its onboard PCB antenna delivers stable wireless connectivity without the need for any external antenna.For hassle-free development, the board includes both a reset button and a bootloader button, ensuring smooth flashing and debugging during your workflow. With support for multiple communication interfaces such as UART, I²C, and SPI, along with a generous set of GPIO pins, the ESP32-C3 SuperMini is an excellent choice for a wide range of embedded and IoT applications.

5V input/output (connects to the USB-C 5V or external 5V supply) |
|
GND |
GND pin |
|
GPIO 0 |
General-purpose I/O, ADC1, PWM |
|
GPIO 1 |
General-purpose I/O, ADC1, PWM |
|
GPIO 2 |
General-purpose I/O ADC1, Strapping Pin (Boot Mode) (avoid for general use) |
|

Strapping Pins
You can still use the strapping pins in your projects, however, you need to take into account the fluctuation of the state of these GPIOs when the ESP32 resets or enters into bootloader mode.
Power Pins
When it comes to power pins, you have one 5V, one 3V3, and a GND pin. The 3V3 pin provides 3.3V from the onboard regulator or accepts 3.3V from an external power source. Similarly, the 5V pin, can be used for input to power the board, or it outputs 5V from the USB power supply.
PWM
All general-purpose GPIOs can output PWM signals.
Analog (ADC) Pins
GPIOs 0, 1, 2, 3, 4, and 5 support analog reading:
UART, I2C, and PWM
Due to the ESP32 multiplexing feature, the UART, SPI, and I2C interfaces can be assigned to nearly any GPIO.
However, when using Arduino IDE, and assuming you’re selecting the ESP32 C3 board in the Boards menu, it will assume the following pins as defaults:
