Product Overview
The ESP32-C3 SuperMini is a high-performance, cost-effective mini IoT development board powered by the Espressif ESP32-C3 WiFi/Bluetooth 5.0 dual-mode chip. Built around a 32-bit RISC-V CPU featuring a single-precision Floating Point Unit (FPU), it delivers powerful computing capabilities for advanced embedded logic and wireless applications.
Engineered for maximum space efficiency, this board is as small as a thumb (22.52 x 18 mm), featuring a single-sided surface mount design ideal for wearable tech, smart sensors, and miniaturized IoT projects. An external antenna port boosts RF signal performance across long distances.
Equipped with 11 digital I/O pins (all supporting PWM), 4 analog ADC pins, onboard blue LED (GPIO8), and serial protocol interfaces (UART, I2C, SPI), the ESP32-C3 SuperMini supports Station, SoftAP, and Hybrid modes with hardware security engines like AES and Secure Boot.
32-Bit RISC-V Core + FPU
Runs up to 160 MHz with a dedicated Floating Point Unit for real-time mathematical operations and responsive logic execution.
Dual-Mode Wireless Connectivity
Supports 2.4GHz IEEE 802.11 b/g/n Wi-Fi and Bluetooth 5.0 (LE) with external antenna capability for extended range.
Ultra Low Power Draw
Deep sleep power consumption as low as ~43 μA makes it ideal for battery-operated wearables and remote sensor nodes.
Rich Hardware Interfaces
Offers 11 GPIOs (PWM enabled), 4 ADC input channels, 2×UART, 1×I2C, and 1×SPI serial communications.
Hardware Security Suite
Built-in accelerators for AES-128/256, Hash, RSA, digital signature, and secure boot hardware encryption.
Ultra-Compact & SMT Ready
Measures just 22.52x18mm with single-sided components for easy surface mounting directly on user PCBs.
