ESP32-C3 Development Board ESP32 Supermini Development Board ESP32 Development Board WiFi Bluetooth

Esp32c3supermini Is an IoT Mini Development Board Based on Espressif ESP32-C3 WiFi/Bluetooth Dual-Mode Chip. ESP32-C3 Is a 32-Bit RISC-V CPU, Including FPU (Floating Point Unit), Which Can Perform 32-Bit Single-Precision Operations and Has Powerful Computing 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 the Signal Strength of Wireless Applications. It Also Has a Small and Exquisite Appearance and Combines a Single-Sided Surface Mount Design. It Is Equipped with a Variety of Interfaces, with 11 One Digital I/O That Can Be Used as the PWM Pin and 4 One Analog I/O That Can Be Used as the ADC Pin. It Supports Four Serial Interfaces, Including UART, I2C, and SPI. There Is Also a Small Reset Button and One Boot Loader Mode Button on the Board.

Based on these features, ESP32C3 Super Mini is positioned as a high-performance, low-power, cost-effective IoT mini development board suitable for low-power IoT applications and wireless wearable devices.

External Power Supply

If external power is needed, simply connect the + terminal of the external power supply to the 5V position and ground to negative.(Supports 3.3~6V power supply).Remember that when connecting an external power source, you cannot use USB; you can only choose one between USB and external power.

Enter download mode: Press and hold the ESP32C3's BOOT button, then press the RESET button, release the RESET button, and then release the BOOT button. At this time, the ESP32C3 will enter download mode.(Each time you connect, you need to re-enter download mode. Sometimes pressing once causes the port to become unstable and disconnects; you can judge by the port identification sound.)
