ESP32-C3 Ultra-Mini Development Board Kit with Antenna: Low-Power High-Performance WiFi and Bluetooth5 for Arduino IoT Projects

ESP32-C3 Super Mini Development Board Kit + Antenna Low Power High Performance WiFi Bluet-ooth 5.0 Applicable to Ardui+no IoT Project

ESP32-C3 is a low-power, high-performance Wi Fi wireless communication chip launched by Espressf-Systems, and is a new member of the ESP32 series. It focuses on providing reliable Wi Fi connectivity and rich peripheral support, suitable for various Internet of Things (IoT) applications.

Product parameters: Powerful CPU: ESP32-C3, 32-bit RISC-V single-core processor running up to 160 MHz WiFi: 802.11b/g/n protocol, 2.4GhHz, supports Station mode, SoftAP mode, SoftAP+Station mode, mixed mode Blue-tooth: Bluetooth5.0 Ultra-low power consumption: Deep sleep power consumption is about 43μA Rich board resources: 400KB SRAM, 384KB ROM and built-in 4M flash Chip model: ESP32C3FN4 Ultra-small size: as small as thumb (22.52x18mm) Classic form factor for wearables and small projects Robust security features: Crypto hardware accelerator supporting AES-128/256, hashing, RSA, HMAC, digital signatures and secure boot Rich interfaces: 1xI2C, 1xSPI, 2xUART, 11xGPIO(PWM), 4xADC Single-sided component, surface mount design Onboard LED blue light: GPIO 8 pins

If external power supply is required, simply connect the external power supply+level to the 5V position and connect the GND to the negative pole. (Supports 3.3-6V power supply).

Note: when connecting to an external power source, USB cannot be connected, and only one can be selected 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 point, ESP32C3 will enter download mode. (Every time you connect, you need to re-enter the download mode. Sometimes, if you press it once, the unstable port will disconnect, which can be determined by identifying the sound through the port.)
