Headline: ESP32-C3 Mini: Your Compact, RISC-V Powered IoT Canvas with WiFi & Bluetooth 5.0. Headers Included, Ready for Your Custom Build.

Key Features & Benefits

🔄 Modern RISC-V 32-Bit Core: Ditch the traditional architecture. Features a 160MHz single-core RISC-V processor with FPU, offering powerful, efficient, and open-source computing for modern IoT applications.

🔌 Ultimate DIY Flexibility (Headers Unsoldered): Headers are included but NOT pre-soldered. Choose to solder on straight/right-angle headers or wire directly for the most compact designs. It’s a blank slate for your creativity.

📶 Robust Dual Wireless: Integrated WiFi 802.11b/g/n and Bluetooth 5.0 LE provide versatile connectivity. Features an external antenna connector (IPEX) for enhanced range when needed (antenna sold separately).

🔋 Ultra-Low Power Champion: With a deep sleep current as low as 43μA, it's ideal for battery-powered sensors, wearables, and devices that need to run for months or years.

📐 Incredibly Compact Footprint: Measuring just 22.52mm x 18.0mm, this thumb-sized board delivers full-featured performance for space-constrained projects.

Product Description
Meet the ESP32-C3 Mini: a next-generation IoT development board that packs a modern RISC-V core, dual wireless connectivity, and ultra-low power into a tiny form factor. Sold without pre-soldered headers, it gives you the freedom to integrate it seamlessly into your project, whether you're creating a sleek wearable, a dense sensor array, or any custom connected device.

🚨 Important Notes / Setup Guide (Read Before You Start!)

❗【Headers & Soldering Required】: This board ships WITH headers in the bag, but they are NOT attached. Basic soldering is required to use the GPIO pins. If you cannot solder, please purchase the "Presoldered" version.

⚠️ Antenna Not Included: For best WiFi/Bluetooth range, an external antenna is recommended but NOT included. The board has an IPEX connector (U.FL compatible). Ensure you purchase a 2.4GHz antenna separately if needed.

🔧 Development Environment: Program it easily using the Arduino IDE (with ESP32 board support) or the official ESP-IDF framework for full control.

⚡ Power Supply Warning: The board operates at 3.3V. DO NOT apply 5V directly to the GPIO pins or the 3.3V pin. Use a stable 3.3V regulated power supply or a 5V-to-3.3V regulator (like an AMS1117) if supplying 5V via USB.

📚 Pinout & Compatibility: While functionally rich, the pin count is limited. Study the pinout diagram carefully. It is not directly pin-to-pin compatible with classic boards like the NodeMCU or Wemos D1 Mini, but shares the same ESP32 ecosystem and Arduino core support.
