Kincony A16 Smart Switch Controller
Kincony KC868-A16 – ESP32-Based WiFi & Ethernet Smart Controller
The Kincony KC868-A16 is a high-capability smart controller designed for DIY home automation, small commercial projects, and advanced automation setups. Powered by the ESP32 (ESP-WROOM-32), it supports Wi-Fi, Bluetooth, and wired Ethernet connections, offering flexibility for both wireless and wired applications. With 16 MOSFET outputs, 16 digital optoisolated inputs, analog inputs, RS485, and 433 MHz wireless module support, the KC868-A16 provides extensive connectivity and control options for relays, sensors, actuators, and other devices.
Designed for compact integration, the KC868-A16 features an accessible USB Type-C port for programming, a robust enclosure, and optional expansion via the KC868-E16 relay module. Its modular design and broad feature set make it ideal for complex automation projects, including environmental monitoring, lighting control, irrigation systems, and more.
