Description

The ESP32-C3 Super Mini is a compact development board featuring the ESP32-C3 chip with built-in Wi-Fi and Bluetooth. Unlike other ESP32 board models, this one is a single-core chip. It has a very small footprint and is optimized for low power consumption, drawing only around 43µA in deep sleep mode, according to the datasheet. The board has 16 pins, with 11 programmable GPIOs that support ADC, PWM, UART, I2C, and SPI.

Key Features and Improvements

• Processor: 32-bit RISC-V CPU running up to 160 MHz

• IEEE 802.11b /g/n WiFi and Bluetooth 5 (LE) protocols

• 400KB SRAM, 384KB ROM and built-in 4M flash

• Compact SMD antenna

• 11 GPIOs that support the following interfaces: 4 ADC pins, PWM, UART, I2C, SPI

• Onboard LED on GPIO 8

• Reset and Boot buttons

• Ultra low power consumption: as low as 43uA in deep sleep mode

• Small form factor
