Q: How to enter the download module?Answer: Press the Boot button of ESP32C3, then press the RESET button, release the REset button, and release the Boot button. At this time, ESP32C3 will enter the download mode.(Each connection needs to enter the download mode again. Sometimes press it again, the port is unstable and disconnect, and you can judge the sound by the port)

Q: Why can't you monitor?Answer: ESP32C3SUPERMINI/ESP32S3PICO/ESP32S2PICO serial port cannot be printed. Solution: Under ARDUINO environment, use direct USB to open CDC on boot, use USB to read CDC on Boot (the fundamental different motherboard model selection)

Q: How to supply external power?Answer the external power supply only needs to connect the external power+level to 5V, and the GND is connected to the pole.(Support 3.3 ~ 6V power supply).Remember to connect to the external power supply, you cannot connect to USB, USB and external power supply can only choose one

If external power supply is needed, you only need to connect the external power+level to 5V, and the GND is extremely negative.(Support 3.3 ~ 6V power supply).Remember that when connecting external power, you cannot connect to USB. USB and external power supply can only be selected.

Enter the download mode: Hold down the Boot button of ESP32C3, then press the reset button, release the RESET button, and release the Boot button. At this time, ESP32C3 will enter the download mode.(Each connection needs to enter the download mode again. Sometimes press it again, the port is unstable and disconnect, and you can judge the sound by the port)

ESP32C3SUPERMINI is an IOT mini development board based on ESP32-C3 WIFI/Bluetooth dual-mode chip.ESP32-C3 is a 32-bit RISC-V CPU, which contains FPU (floating-point unit), which can perform 32-bit single-precision operations and has strong computing power.It has excellent RF performance and supports IEEE 802.11 B/G/N WiFi and Bluetooth 5 (Le) protocol.The board is equipped with an external antenna, which can enhance the signal strength of wireless applications.It also has a small and exquisite shape and combined with single -sided surface installation design.It is equipped with a wealth of interfaces, with 11 digital I/O for PWM pins and 4 analog I/O for the ADC pin.It supports four serial interfaces such as UART, I2C and SPI.There is also a small reset button and a guidance loading program button on the board.

Based on the above characteristics, ESP32C3Supermini is positioned as a high -performance, low power consumption, and cost -effective IoT mini development board, which is suitable for low -power IoT applications and wireless wearable applications.
