ESP32 Super Mini Development Board ESP32-C3 with 2.4G WiFi Antenna ESP32C3 Wi-Fi+BT Module for Arduino IoT

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.)

Package includes:
1 X ESP32C3 ESP32 Super Mini Development Board
1 X 2.4G WiFi Antenna
