This micro marvel crams the powerful ESP32-C3, a single-core RISC-V powerhouse with 400KB of SRAM, into a compact 1.3in. x 0.7in. board. Clocking in at 160MHz, it's ready to tackle your projects quickly and efficiently. Forget wires and soldering headaches – the Pro Micro ESP32-C3 embraces the simplicity of the Qwiic connector. Just plug and play any Qwiic sensor and watch your projects come alive with environmental data, motion detection, or whatever your imagination conjures. And stay connected, wherever you are, with built-in WiFi and Bluetooth® 5 (LE). But the Pro Micro ESP32-C3 isn't just about small talk. Its 22 programmable GPIOs, accessible through handy castellated headers, unlock a multitude of possibilities. From tinkering with LEDs and servos to crafting intricate sensor networks, this tiny titan has the muscle to handle it all. And thanks to support for a range of protocols like ADC, SPI, UART, and I2C, the creative toolbox keeps expanding. The Pro Micro ESP32-C3 taps into the power of Espressif's open-source ESP-IDF, a robust ecosystem brimming with libraries, tools, and a supportive community. Plus, you can leverage the familiar Arduino IDE for a smooth development experience. So whether you're building a wearable masterpiece, a chatty IoT gadget, or a robotic friend, the SparkFun Pro Micro ESP32-C3 is your pint-sized partner in innovation. Grab one today and let your small-scale dreams take flight! Note: Unlike other ESP32 boards, this device requires user interaction to program. To program the device, hold down BOOT while resetting it. This is a simple process, but it is not automatic. The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
