ESP32-C3 DevKitM-01 - 4 MB SPI Flash - ESP32-C3-MINI-1

The ESP32-C3-DevKitM-01 is an entry-level development board featuring the ESP32-C3-MINI-1 module, a powerful Wi-Fi and Bluetooth LE MCU designed for various IoT applications including embedded systems, smart homes, and wearable electronics. This version includes 4MB SPI Flash and no PSRAM, equipped with a PCB antenna for reliable connectivity.

At its core, the board utilizes the ESP32-C3FN4 chip with a RISC V core architecture, differentiating it from traditional ESP32 boards. It supports Arduino and ESP IDF development environments, though CircuitPython is not yet supported.

Key peripherals are accessible via pin headers on both sides of the board for easy interfacing and breadboard compatibility. Multiple power supply options include Micro-USB, 5V and GND pins, or 3.3V and GND pins, with Micro-USB recommended.

Features include:

• ESP32-C3-MINI-1 module with 4MB embedded flash
• RISC V 32-bit core with Wi-Fi and Bluetooth LE
• Multiple peripheral interfaces: UART, I2C, I2S, SPI, PWM, ADC, USB Serial/JTAG
• Micro-USB port for power and communication
• USB-to-UART bridge supporting up to 3 Mbps transfers
• Boot and reset buttons for firmware download and system restart
• Addressable RGB LED driven by GPIO8
• Compact size and breadboard-friendly pin headers

This board is ideal for developers looking to leverage the ESP32-C3's capabilities in compact IoT projects and embedded applications.
