ESP32-C3 SuperMini development board, 3.3V, ideal for IoT applications and portable devices, based on the Espressif ESP32-C3 chip, which offers high performance thanks to the 32-bit RISC-V processor, capable of fast operations and calculations.
The board includes support for WiFi 802.11 b/g/n and Bluetooth 5 (LE), providing excellent connectivity for wireless projects.
Its design is ultra-compact, weighing only 3 grams, with a single layer of surface-mounted components (SMD), and the integrated antenna improves the wireless signal. The USB connection is Type-C (type C) and includes a voltage regulator to lower it from 5V via USB to 3.3V (the operating voltage of the board).
It offers 11 digital pins that can be used as PWM and 4 analog pins compatible with ADC. It supports UART, I2C and SPI interfaces, making it extremely versatile for various IoT applications.
In addition to low power consumption, the ESP32-C3 SuperMini includes advanced security features, such as hardware acceleration for AES-128/256 encryption, digital signatures, and Secure Boot, making it suitable for secure and efficient systems.

Use:
The board can be powered with 5VDC via the USB-C jack or the 5V pin, but it is ONLY compatible with 3.3V logic voltage, which is why you should not use it with peripherals that exceed 3.3VDC.
Use Arduino IDE, ESP-IDF or PlatformIO for development and programming the board. For Arduino IDE, the following link will be added in "Additional Boards":
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json
From the list of available boards in Tools->Board, choose the ESP32 Arduino->ESP32C3 Dev Module board.
Bootloader mode: To upload firmware, hold down the BOOT button while powering on the board. Alternatively, the Enable option can be selected from the Tools->USB CDC on Boot menu, which allows code to be uploaded without having to enter the bootloader manually.
The GPIO8 LED indicates the board status. Use UART for debugging.
