Q:Why can't can't monitor? A: esp32c3supermini/esp32s3pico/esp32s2pico serial port can not be printed, the solution: arduino environment, the use of direct-connected usb remember to open the cdc on boot, the use of usb to the serial port remember to turn off the cdc on boot (fundamentally different motherboard models can be selected)

Q: How to supply power externally? A external power supply only need to access the external power supply + level 5V position, GND connected to the negative pole. (Support 3.3 ~ 6V power supply). Remember to connect the external power supply, can not access the USB, USB and external power supply can only choose a

If you need external power supply, you only need to connect the external power supply + level to the 5V position, GND to the negative pole. (Support 3.3~6V power supply). Remember that when connecting the external power supply, you can not access the USB, USB and external power supply can only choose one.

Entering 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 time, ESP32C3 will enter the download mode. (You need to re-enter the download mode every time you connect, sometimes press it once, the port is unstable and will disconnect, you can judge by the port recognition sound)

ESP32C3SuperMini is an IoT mini development board based on the ESP32-C3 WiFi/Bluetooth dual-mode chip.ESP32-C3 is a 32-bit RISC-V CPU containing FPU (Floating Point Unit) for 32-bit single-precision arithmetic with powerful computational capabilities. 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 features a small and compact form factor combined with a single-sided surface mount design. It is equipped with a rich set of interfaces, with 11 digital I/Os that can be used as PWM pins and 4 analog I/Os that can be used as ADC pins, and it supports four serial interfaces, including UART, I2C, and SPI. There is also a small reset button and a bootloader mode button on the board.

Combining the above features, ESP32C3SuperMini is positioned as a high-performance, low-power, cost-effective IoT mini development board for low-power IoT applications and wireless wearable applications.
