"description": "<p>The ESP32-C3-0.42LCD is an ESP32 C3 / RP2040 Raspberry Pi Pico Development board with 0.42 inch LCD risc-v WiFi Bluetooth.</p><p>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 core. There’s a minimum number of pins on this chip, it’s specifically designed to be low cost and for simpler projects than ESP32-Sx or ESP32 classics with their large 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.</p><p>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 Quad SPI interfaces. There is no DAC or native capacitive touch.</p><p>With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.</p><p><strong>Specifications</strong></p><ul> <li>Based ESP32-C3FH4 WIFI &amp; Bluetooth LE RISC-V Single-Core CPU</li> <li>Type-C USB</li> <li>4MB Flash</li> <li>11x IO</li> <li>1x1.0-4P connector(GND,3V3,SDA(GPIO5),SCL(GPIO6))</li> <li>1x RGB(GPIO2)</li> <li>1xLED(3.3V Power Supply)</li> <li>1xReset button(CHIP_EN,great for restarting your program or entering the ROM bootloader)</li> <li>1xBoot button(GPIO9,entering the ROM bootloader or for user input)</li> <li>3.3V Regulator with 500mA peak output</li> <li>Ceramic Antenna</li></ul><h2 id=\"purchase\">Purchase</h2><ul> <li><a href=\"https://www.aliexpress.us/item/3256804679132291.html\">Aliexpress</a></li></ul>"
