Introduction

ESP32C3SuperMini is the 1 IoT mini development board based on Espressif ESP32-C3 WiFi/Bluetooth dual mode chip. ESP32-C3 is the 1 32-bit RISC-V CPU, including the FPU (floating point unit), can be 32-bit single precision operations, with strong computing power. It has excellent RF performance and supports IEEE 802.11 B/g/n WiFi and Bluetooth 5 (LE) protocols. The board comes with an external antenna to enhance signal strength for wireless applications. It also has a small and delicate shape combined with a single-sided surface mount design. It is equipped with a rich interface, with 11 digital I/OS that can be used as PWM pins and 4 analog I/OS that can be used as ADC pins. It supports 4 serial interfaces such as UART, I2C, and SPI. There is also a small reset button and a bootloader mode button on the board.

Based on the above characteristics, the ESP32C3SuperMini 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.

External power supply

If external power supply is required, only the external power supply level is connected to the 5V position, and GND is connected to the negative pole. (Support 3.3~6V power supply). Remember that when connecting an external power supply, USB cannot be connected, and only one USB and external power supply can be selected.

Enter the download mode: press and hold the BOOT button of the ESP32C3, then press the RESET button, release the RESET button, and then release the BOOT button. At this time, the ESP32C3 will enter the download mode. (You need to re-enter the download mode every time you connect, sometimes press the 1 button, the port will be disconnected if the port is unstable, which can be judged by the port recognition sound)
