M5STACK SwitchC6 Smart Wireless Switch

OUTLINE

• StickC6 is a smart wireless switch product based on a single-wire energy harvesting scheme that extracts energy via leakage from the live wire and uses a supercapacitor to supply stable DC power to the system.
• The product integrates a high-efficiency DC-DC conversion circuit, precise power filtering design, and an ESP32-C6-MINI-1 wireless control core, supporting dual-mode wireless communication with 2.4GHz
• Wi‑Fi and BLE, while utilizing high-current MOSFETs for efficient and safe AC load switching.
• It features a dedicated external switch interface for connecting physical buttons or sensors, enabling both manual and automatic control; an integrated download indicator LED provides visual feedback during firmware burning and upgrades, and a program download pad is provided for easy firmware updates and debugging.
• Additionally, the product includes a 1.25-3P interface used as an IO expansion port for the ESP32-C6-MINI-1, facilitating the addition of more peripheral functions.
• StickC6 is ideally suited for smart home, industrial automation, and IoT applications, offering a highly efficient, safe, stable, and easily expandable smart switch solution.
