Product Highlights: Why Choose ESP32C3SuperMini? Dual Wireless Connectivity: Supports IEEE 802.11 b/g/n WiFi / Bluetooth 5.0 (LE) for stable IoT data transmission, perfect for smart home, wearable devices, and wireless control projects. Powerful RISC-V CPU: 32-bit RISC-V processor with built-in FPU (Floating-Point Unit) – enables 32-bit single-precision floating-point operations, delivering strong computing performance for complex tasks. Enhanced Signal Strength: Equipped with an external antenna to boost WiFi/Bluetooth signal, solving weak connectivity issues in long-distance or complex environments. Ultra-Small / Compact Design: Only 22.52/18mm (thumb-sized!) with single-sided SMD (Surface Mount Device) layout – easy to embed into small devices like wearables, mini sensors, or space-limited IoT projects. Low Power Consumption: Optimized power management, ideal for battery-powered applications (deep sleep current as low as /43μA) – extends device runtime significantly.
