ESP32-C6 Expansion Board

Overview

This project features a modular expansion board based on the ESP32-C6 microcontroller, designed to showcase advanced wireless connectivity and interface flexibility for proof-of-concept embedded systems. The board includes Wi-Fi 6, Bluetooth 5, and 802.15.4 (Thread/Zigbee) support, making it suitable for modern IoT applications. In addition to its wireless capabilities, the board exposes key communication interfaces like QSPI, SPI, I2C, and UART, enabling it to serve as a powerful, plug-and-play module in larger prototype systems.

Features

• ESP32-C6 MCU – RISC-V single-core processor with Wi-Fi 6, BLE 5, Thread, and Zigbee support
• QSPI Interface – For high-speed flash memory or display integration
• SPI, I2C, UART – Standard communication protocols for versatile interfacing
• Low Power Operation – Ideal for battery-powered and energy-conscious applications
• Modular Design – Created for reuse across multiple proof-of-concept hardware projects

Applications

• IoT Prototyping – Wireless communication for smart sensors and devices
• Home Automation – Thread/Zigbee-enabled devices with cloud connectivity
• Industrial Monitoring – Robust wireless links in noisy environments
• Education & Research – Hands-on embedded systems development

Getting Started

Hardware Requirements

• ESP32-C6 Expansion Board
• Host MCU or baseboard (if applicable)
• USB-C or serial programmer (if needed)
• 3.3V power supply

Software Requirements
