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<br> It has built-inUSB-to-Serial, but not native USB - it cannot act as a keyboard or disk drive.<br> The chip used here has 4MB of Flash memory, 400 KB of SRAM.<br> 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.<br> 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.<br> Features<br> based ESP32-C3FH4 WIFI & Bluetooth LE RISC-V Single-Core CPU<br> Type-C USB<br> 4MB Flash<br> 11x IO<br> 1x1.0-4P connector(GND,3V3,SDA(GPIO5),SCL(GPIO6))<br> 1x RGB(GPIO2)<br> 1xLED(3.3V Power Supply)<br> 1xReset button(CHIP_EN,great for restarting your program or entering the ROM bootloader)<br> 1xBoot button(GPIO9,entering the ROM bootloader or for user input)<br> Compatible with MicroPython, for and ESP-IDF<br> 3.3V Regulator with 500mA output<br> size: 23.5 x 18 mm<br> Material: PCB<br> colour: purple<br> Package Contents:<br> 1 x ESP32 C3 Development Board<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
