ESP32-C3 SuperMini

Description

The ESP32-C3 SuperMini is an ultra-compact, high-performance development board built around Espressif’s 32-bit RISC-V single-core ESP32-C3 processor, which also features integrated Wi-Fi and Bluetooth dual-mode capabilities. Designed for low-power IoT and wireless wearable applications, it offers robust connectivity and extensive peripheral support within a tiny footprint, all powered by its efficient RISC-V core.

Processor & Memory

• CPU: ESP32-C3, a 32-bit RISC-V single-core processor with a Floating Point Unit (FPU), capable of up to 160 MHz operating frequency.
• Memory: Integrated 400KB SRAM, 384KB ROM, and 4MB of embedded SPI flash memory.

Wireless Connectivity

• Wi-Fi: Supports IEEE 802.11 b/g/n protocol (Wi-Fi 4) at 2.4 GHz. Operates in Station mode, SoftAP mode, SoftAP+Station mode, and hybrid mode.
• Bluetooth: Bluetooth 5 (LE) with support for long-range (LR) communication and Bluetooth LE SIG Mesh.

Power & Low-Power Features

• Input Voltage: Supports 5V power input via USB-C or 3.3V-6V via external power supply (5V pin). Note: USB and external power supply cannot be used simultaneously.
• Ultra-Low Power Consumption: Deep sleep power consumption is approximately 43μA, ideal for battery-powered applications.

Interfaces & Peripherals

• Digital I/O: 11 programmable GPIOs, which can also be used as PWM pins.
• Analog I/O: 4 analog input pins (ADC).
• Serial Interfaces: Includes 1x I2C, 1x SPI, and 2x UART interfaces for versatile peripheral integration.
• On-board Components: Features a blue LED (connected to GPIO8), a reset button, and a boot button for easy programming and debugging.
• Security: Hardware-based encryption accelerators supporting AES-128/256, hashing, RSA, HMAC, digital signatures, and secure boot for robust device protection.
• Other: Supports JTAG for debugging, I2S for audio, and a temperature sensor.

Form Factor & Development

• Ultra-Small Size: Highly compact design (approx. 22.52 x 18mm), making it suitable for space-constrained projects and wearable devices.
• Development Environment: Compatible with Espressif’s ESP-IDF and Arduino IDE for streamlined development.
