ESP32-C3, a 32-bit RISC-V single-core chip running at up to 160 MHz. It packs 2.4GHz WiFi and Bluetooth 5 (LE) onto a board just 22.5 x 18 mm, with a USB-C port, an onboard PCB antenna, and pre-soldered headers ready for the breadboard. Ideal for compact IoT, sensor, and wireless projects where space is tight.\u003c\/p\u003e\n\n            \u003cul class=\"nzn-checks\"\u003e\n              \u003cli\u003eESP32-C3 32-bit RISC-V single core, up to 160 MHz\u003c\/li\u003e\n              \u003cli\u003e2.4GHz WiFi (802.11 b\/g\/n) and Bluetooth 5 (LE)\u003c\/li\u003e\n              \u003cli\u003eUSB-C connector with pre-soldered headers\u003c\/li\u003e\n              \u003cli\u003e4 MB flash, 400 KB SRAM, 384 KB ROM\u003c\/li\u003e\n              \u003cli\u003e11x GPIO (PWM), 4x ADC, I2C, SPI, 2x UART\u003c\/li\u003e\n              \u003cli\u003eDeep sleep current around 43 uA\u003c\/li\u003e\n              \u003cli\u003eTiny 22.5 x 18 mm board with onboard PCB antenna\u003c\/li\u003e\n              \u003cli\u003eWorks with Arduino IDE, PlatformIO, MicroPython and ESPHome\u003c\/li\u003e\n            \u003c\/ul\u003e\n          \u003c\/div\u003e\n\n          \u003cdiv class=\"nzn-started\"\u003e\n            \u003ch3\u003eGetting Started in the Arduino IDE\u003c\/h3\u003e\n\n            \u003cdiv class=\"nzn-step\"\u003e\n              \u003cspan\u003e1\u003c\/span\u003e\n              \u003cdiv\u003e\n                \u003cstrong\u003eInstall the ESP32 package\u003c\/strong\u003e\n                \u003cp\u003eOpen Boards Manager, search \"esp32\" by Espressif, and install it.\u003c\/p\u003e\n              \u003c\/div\u003e\n            \u003c\/div\u003e\n\n            \u003cdiv class=\"nzn-step\"\u003e\n              \u003cspan\u003e2\u003c\/span\u003e\n              \u003cdiv\u003e\n                \u003cstrong\u003eSelect the board\u003c\/strong\u003e\n                \u003cp\u003eGo to Tools, then Board, and choose \"ESP32C3 Dev Module\".\u003c\/p\u003e\n              \u003c\/div\u003e\n            \u003c\/div\u003e\n\n            \u003cdiv class=\"nzn-step\"\u003e\n              \u003cspan\u003e3\u003c\/span\u003e\n              \u003cdiv\u003e\n                \u003cstrong\u003ePlug in over USB-C\u003c\/strong\u003e\n                \u003cp\u003eConnect a USB-C data cable and pick the COM port that appears under Tools, then Port.\u003c\/p\u003e\n              \u003c\/div\u003e\n            \u003c\/div\u003e\n\n            \u003cdiv class=\"nzn-step\"\u003e\n              \u003cspan\u003e4\u003c\/span\u003e\n              \u003cdiv\u003e\n                \u003cstrong\u003eUpload your sketch\u003c\/strong\u003e\n                \u003cp\u003eHit upload.
