Product  Features

ESP32C3SuperMini is an IoT mini development board based on Espressif

ESP32-C3WiFi/Bluetooth dual-mode chip.

ESP32-C3 is a 32-bit RISC-VCPU that includes FPU (floating point unit) for 32-bit single-precision operations and has powerful computing power. It has excellent RF performance and supports IEEE 802.11b/g/nWiFi and Bluetooth 5 (LE) protocols. The board comes with an external antenna to enhance the signal strength of wireless applications. It also has a small and exquisite shape combined with a single-sided surface mount design. It is equipped with a rich interface, with 11 digital I/0s that can be used as PWM pins and 4 analog I/0s that can be used as ADC pins. It supports four 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 features, 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.

Product  Descriptions

External power supply

If external power supply is needed, just connect the external power supply + level to the 5V position, and GND to the negative pole. (Supports 3.3~6V power supply). Remember that when connecting the external power supply, you cannot connect to USB. You can only choose one between USB and external power supply.

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 time, ESP32C3 will enter download mode. (You need to re-enter download mode every time you connect. Sometimes, if you press it once, the port will be unstable and disconnected. You can judge it by the port recognition sound)
