Compatibility
This board is programmable using Arduino IDE, ESP-IDF, or MicroPython. 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.
Wiring Notes
Power 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.
Why Buy from Compoden
Every 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.
Is this compatible with Arduino IDE?
Yes, 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.
Can I use this board for battery-powered projects?
Absolutely. 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.
Does the board have a built-in antenna?
Yes, 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.
