The ESP32-C3-DevKitC-02 is an entry-level RISC V development board equipped with the ESP32-C3-WROOM-02, a powerful, generic Wi-Fi + Bluetooth LE MCU module that features a rich set of peripherals, yet an optimized size. It's an ideal choice for a wide variety of application scenarios related to the Internet of Things (IoT), such as embedded systems, smart homes, wearable electronics, etc. ESP32-C3-DevKitC-02 comes with a PCB antenna. This version is equipped with the ESP32-C3-WROOM-02 with 4MB SPI Flash and no PSRAM.
Please note: The C3 is similar to the ESP32 - but uses RISC V as a core, not Tensilica, and has Bluetooth LE (not classic!) However, there is minimal support for this dev board. For example, as of the time of this writing, there is no CircuitPython support - only Arduino and ESP IDF! Please purchase if you're doing development with the C3, and recognize that it's a different core than the classic ESP32s most folks have used.
Most of the I/O pins on the module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-C3-DevKitC-02 on a breadboard.
At the core of the module is ESP32-C3, which has a 32-bit RISC-V single-core processor. 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 are three mutually exclusive ways to provide power to the board:
It is recommended to use the first option: Micro-USB Port.
