ESP32 C3 SuperMini Development Board ESP32-C3 WiFi Bluetooth Module For Arduino

ESP32 C3 SuperMini is an IoT mini development board based on the Espressif ESP32-C3 WiFi/Bluetooth dual-mode chip. ESP32-C3 is a 32-bit RISC-V CPU that includes an FPU (floating point unit) and can perform 32-bit single precision operations with powerful computing power. It has excellent RF performance and supports IEEE 802.11 b/g/n WiFi and Bluetooth 5 (LE) protocol. This board comes with an external antenna to enhance the signal strength of wireless applications. It also has a compact and exquisite appearance combined with a single-sided surface mount design. It is equipped with rich interfaces, including 11 digital I/Os that can be used as PWM pins and 4 analog I/Os that can be used as ADC pins. It supports four serial interfaces: UART, I2C, and SPI. There is also a small reset button and a boot loader mode button on the board. Powerful CPU: ESP32-C3, 32-bit RISC-V single core processor, running at frequencies up to 160 MHz WiFi: 802.11b/g/n protocol, 2.4GHz, supports Station mode, SoftAP mode, SoftAP+Station mode, hybrid mode Bluetooth: Bluetooth 5.0 Ultra low power consumption: Deep sleep power consumption is about 43% μ A Rich board resources: 400KB SRAM, 384KB ROM with built-in 4Mflash. Chip model: ESP32C3FN4 Ultra small size: as small as the thumb (22.52x18mm), classic shape suitable for wearable devices and small projects Reliable security features: Encryption hardware accelerator that supports AES-128/256, hashing, RSA, HMAC, digital signatures, and secure boot Rich interfaces: 1xI2C, 1xSPI, 2xUART, 11xGPIO (PWM), 4xADC Single sided components and surface mount design On board LED blue light: GPIO8 pin 1 * ESP32-C3 Development Board ESP32 Mini WiFi Bluetooth Product parameters Powerful CPU: ESP32-C3, 32-bit RISC-V single-core processor, running frequency up to 160 MHz WiFi: 802.11b/g/n protocol, 2.4GhHz, supports Station mode, SoftAP mode, SoftAP+Station mode, mixed mode Ultra-low power consumption: deep sleep power consumption is about 43μA Rich board resources: 400KB SRAM, 384KB ROM built-in 4Mflash. Ultra-small size: as small as a thumb (22.52x18mm) Classic shape, suitable for wearable devices and small projects Reliable security features: support AES-128/256, hash, RSA, HMAC, cryptographic hardware accelerator for digital signature and secure boot Single-sided components, surface mount design Onboard blue LED: GPIO8 pin Pin diagram 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 the 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)
