ESP32-C3 is a low-cost microcontroller from Espressif that supports 2.4 GHz Wi-Fi and Bluetooth Low Energy ( Bluetooth 5 (LE)).Use RISC V as the There's a minimum number of pins on this chip, it's specifically designed to be low cost and for simpler projects than ESP32- or ESP32 classics with their number of GPIO. Think of it more as an intended replacement to the ESP8266 than to the ESP32 It has built-inUSB-to-Serial, but not native USB - it cannot act as a keyboard or disk drive. The chip used here has 4MB of Flash memory, 400 KB of SRAM. The ESP32-C3 integrates a rich set of peripherals, ranging from UART, I2C, I2S, remote control peripheral, LED PWM controller, general DMA controller, TWAI controller, USB Serial/JTAG controller, temperature sensor, and ADC. It also includes SPI, Dual SPI, and SPI interfaces. There is no DAC or native capacitive touch. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.
