Connect Your Way

NexGen WiFi lets you control relays using Wi-Fi, Bluetooth, or USB, all from one module. Configure everything through a built-in web page and choose the communication method that fits your project - simple to start, powerful when you're ready to scale.

Looking for an 8-channel bluetooth relay? Choose from expandable ProXR models, non-expandable ProXR Lite versions, and DPDT relay options for advanced switching needs.

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.
Please Note: Apple encrypts the Bluetooth signal on an iPhone and iPad therefore bluetooth boards will not communicate with them.  We recommend the web interface option for browser based interface for the iPhone or iPad users.

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.

Choosing Your 8-Channel Bluetooth Relay

Bluetooth Relay8-channel Bluetooth relay boards are available in ProXR Lite and ProXR versions:
  • ProXR Lite - Non-expandable, streamlined design
  • ProXR - Expandable up to 256 relays
Both versions use the same firmware and support the full ProXR Command Set, giving you identical control capabilities. The difference is expandability.

ProXR Lite vs ProXR
  • ProXR Lite: Non-expandable, streamlined design for fixed-size projects
  • ProXR: Expandable up to 256 relays for growing systems
  • Both: Same firmware, same ProXR Command Set, same control features
💡 Relay Pros Pro Tip:
If you think your project might grow, choose the ProXR version. You'll start with 8 relays today and expand up to 256 later - without replacing your controller.
