8 Channel Bluetooth Relay Module is great for controlling your devices over the Bluetooth link without any RF design knowledge. This module is designed to plug into your design seamlessly. Individual relay can be controlled by simple commands. Numato’s 8 Channel Bluetooth Relay Module provides exceptional value for money.
This board has eight onboard 12V relays that can switch up to 7A load. The relays are controlled by a Microchip PIC Microcontroller over Bluetooth link and come with built-in firmware that supports simple commands to control relays and read relay status. This board can easily be controlled by writing the simple serial port applications in VC++, VB, VBA (Word, Excel, etc), Perl, Python, etc. A USB Bluetooth Dongle or Bluetooth integrated PC/Laptop would be sufficient to communicate with this device. A USB connector is available onboard for firmware upgrade.
