ESP32-C3 Supermini Development Board with built-in 4M flash memory

ESP32 C3 super mini board is a powerful IoT mini development board featuring the Espressif ESP32C3 WiFi/Bluetooth dual-mode chip. Explore the possibilities of this 32-bit RISC-V CPU with FPU, which offers impressive computing power. Benefit from excellent RF performance and support for IEEE 802.11 b/g/n WiFi and Bluetooth 5 (LE). With 11 digital I/Os (PWM) and 4 analog I/Os (ADC), the board provides rich interfaces for various applications. Explore the flexibility of four serial interfaces: UART, I2C, and SPI. With a tiny reset button and bootloader mode button, this board is ideal for low-power IoT applications and wireless wearable applications. Discover the power, efficiency, and cost-effectiveness of the ESP32-C3 SuperMini for your projects.

To enable external power supply, connect the positive level of external power supply to the 5V position, and connect the GND to the negative terminal. It supports power supply in the range of 3,3 to 6V. Please note that when connecting external power supply, USB access is not available; only one option can be chosen between USB and external power supply.

To program the ESP32-C3 Super Mini, first hold the BOOT button, then while holding it down, briefly press the RST button. Then you can release the BOOT button. Once you have done this, the ESP32-C3 Super Mini will go into upload mode. You can then upload your sketch via the Arduino IDE.

You can upload your sketch via the Arduino IDE by first selecting the board “ESP32C3 Dev Module” (Note: if you cannot find it, you will need to download the esp32 boards from the board manager first), then selecting the correct COM port and finally uploading your sketch using the arrow at the top.

Once your sketch is uploaded, you need to press the RST button again. This will cause the ESP32-C3 Super Mini to exit upload mode.

Package Includes:

• 1 x ESP32 C3 Supermini Development Board with built-in 4M flash memory
