Product Description:
Product Features
- ESP32C3 SuperMini is an IoT mini development board based on the Espressif ESP32C3 WiFi/Bluetooth dual-mode chip. ESP32-C3 is a 32-bit RISC-V CPU that includes an FPU (floating point unit) that can perform 32-bit single precision operations and has powerful computing power.
- Excellent RF performance and supports IEEE 802.11 b/g/n WiFi and Bluetooth 5 (LE) protocols.
- Compact and exquisite appearance combined with a single surface mount design.
- Equipped with rich interfaces, including 11 digital I/Os that can be used as PWM pins and 4 analog I/Os that can be used as ADC pins.
- Supports four serial interfaces: UART, I2C, and SPI.
- Reset and bootloader mode buttons are mounted on the board.
- ESP32-C3 SuperMini is positioned as a high-performance, low-power, and cost-effective IoT mini development board, suitable for low-power IoT applications and wireless wearable applications.

Attention
If an external power supply is required, simply connect the external power supply positive to the 5V position and connect the GND to the negative pole. (Supports 3.3-6V power supply). Remember that when connecting to an external power source, the USB connection cannot be used. Only one supply input can be connected. Either the USB or an external power supply.
2. Please be careful not to short-circuit the positive and negative electrodes during welding, which may burn out the battery and equipment.
Instructions for use
To enter download mode, press and hold the BOOT button of ESP32C3, then press the RESET button, release the RESET button, and then release the BOOT button. At this point, ESP32C3 will enter download mode. (Every time you connect, you need to re-enter the download mode. Sometimes, if you press it once, the unstable port will disconnect, which can be determined by identifying the sound through the port.)
