The ESP32-C3 SuperMini is a compact, low-power development board based on the ESP32-C3 chip, featuring Wi-Fi and Bluetooth 5 (LE) connectivity. It’s designed for space-constrained projects, offering a 32-bit RISC-V single-core processor with a maximum frequency of 160MHz. The board includes 400KB of SRAM, 384KB of ROM, and 4MB of built-in flash memory.
SPECIFICATIONS:
- Processor: 32-bit RISC-V single-core, up to 160MHz.
- Connectivity: 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE).
- Memory: 400KB SRAM, 384KB ROM, 4MB flash.
- Interfaces: 1x I2C, 1x SPI, 2x UART, 11x GPIO (including PWM), 4x ADC.
- Power: Can be powered via USB-C or 5V/GND pins (3.3-6V).
- Form Factor: Extremely compact, measuring 22.52 x 18 mm.
- Onboard LED: Blue LED on GPIO 8.
- Other Features: Reset and Boot buttons, support for hardware SPI, ADC, and PWM.
- Ultra-low power consumption: Deep sleep power consumption can be as low as 43µA.
POWERING THE BOARD:
- The SuperMini can be powered via the USB-C connector or through the 5V and GND pins.
- When using an external power supply, ensure that it is within the 3.3-6V range.
- When using an external power supply, do not connect the USB-C connection at the same time.
