It works with common sensors and modules over I2C, SPI, and UART, such as BME280, WS2812B LEDs, and SSD1306 OLEDs. Note that all GPIOs operate at 3.3V logic levels; attaching 5V signals may damage the board. Use level shifters if interfacing with 5V peripherals.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003ePower the board via the USB-C port (5V) or by connecting a 3.7V LiPo battery to the VBAT pin. Do not connect 5V directly to any GPIO pin. For I2C devices, external pull-up resistors (typically 4.7kΩ) on SDA and SCL are recommended. GPIO0 and GPIO2 affect boot mode; avoid pulling them low during reset unless you intend to enter programming mode.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino IDE?\u003c\/summary\u003e\u003cp\u003eYes, you can program the ESP32-C3 using Arduino IDE by installing the ESP32 board package (use the stable release URL). Select \"ESP32C3 Dev Module\" as the board.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use this board for battery-powered projects?\u003c\/summary\u003e\u003cp\u003eAbsolutely. The ESP32-C3 supports deep sleep with current consumption below 5 µA, making it suitable for battery operation. Connect a 3.7V LiPo cell to the VBAT pin and use an external charger module for recharging.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes the board have a built-in antenna?\u003c\/summary\u003e\u003cp\u003eYes, it features an on-board ceramic antenna for Wi-Fi and BLE, so no external antenna is needed. The compact design maintains a small footprint.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
