Selecting the Proper Amperage

For more information on selecting a board with the correct relay amperage for your application see Choosing a Proper Amperage.

This 16-channel Bluetooth relay board gives you 16 individually controlled relays and the ability to expand up to 256 relays, making it ideal for scalable automation, industrial control, and custom relay projects.

NextGen Bluetooth Relay Interface

The NexGen Bluetooth/WiFi interface lets you control relays wirelessly over a Bluetooth connection. Using the Bluetooth Serial Port Profile (SPP), the board appears as a standard COM port on your computer, making wireless communication simple and familiar.

Bluetooth settings such as the device name and PIN can be configured through the built-in web interface using WiFi Soft AP mode. This means you enable and manage Bluetooth using the same easy setup process as your WiFi features.

NexGen Bluetooth Communication

The NexGen Bluetooth/WiFi communications module modernizes connectivity by combining WiFi, Bluetooth, USB, and MQTT into a single powerful interface. The onboard firmware focuses on essential features while remaining flexible enough for a wide range of automation and control applications.
