ESP32-C3 Super Mini is an IoT mini development board based on the Espressif ESP32-C3 Wi-Fi/Bluetooth dual-mode chip. The ESP32-C3 features a 32-bit RISC-V CPU with an integrated FPU (Floating Point Unit), supporting 32-bit single-precision operations and delivering strong computing performance. It offers excellent RF performance, supporting IEEE 802.11 b/g Wi-Fi and Bluetooth 5 (LE) protocols. An external antenna is included to enhance wireless signal strength. The board features a compact, refined form factor with a single-sided component layout, ideal for wearables and space-constrained projects. It provides rich peripheral interfaces: - 11 digital I/O pins, configurable as PWM outputs - 4 analog I/O pins, usable as ADC inputs - 1 I²C interface - 1 SPI interface - 2 UART interfaces - Reset button and bootloader mode button Key specifications: - Processor: ESP32-C3, 32-bit RISC-V single-core, up to 160 MHz - Wi-Fi: 802.11 b/g, 2.4 GHz - Bluetooth: Bluetooth 5.0 LE - Ultra-low power consumption: ~43 µA in deep sleep mode - Memory: 400 KB SRAM, 384 KB ROM - Built-in 4 MB Flash - Chip model: ESP32-C3FN4 - Dimensions: Compact size, approximately thumb-sized - Onboard LED: Blue, connected to GPIO8 - Material: PCB with plastic components Package includes: - 1 × ESP32-C3 development board (pin headers not soldered) Note: Color may vary slightly due to screen settings and lighting conditions.
