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 floating-point operations. It delivers strong computing performance and excellent RF capabilities, supporting IEEE 802.11 b/g Wi-Fi and Bluetooth 5 (LE) protocols. The board includes an external antenna to improve wireless signal strength. Its compact, single-sided design makes it ideal for wearables and small-scale projects. The board provides rich peripheral interfaces: - 11 digital I/O pins (supporting PWM) - 4 analog input pins (supporting ADC) - 1 I²C interface - 1 SPI interface - 2 UART interfaces - Reset button and bootloader 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 LED connected to GPIO8 Material: Plastic Package includes: 1 × ESP32-C3 development board (pin headers not soldered) Note: Color may vary slightly due to screen settings and lighting conditions.
