Onboard USB Connector for firmware upgrade.

1 Analog Input Channel(Multiplexed with GPIOs).

A USB connector is available onboard for firmware upgrade. A USB Bluetooth Dongle or Bluetooth integrated PC/Laptop would be sufficient to communicate with this device. This board can easily be controlled by writing the simple serial port applications in VC++, VB, VBA (Word, Excel, etc), Perl, Python, etc. 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.

Screw the back-box in position (see picture on right). This board has eight onboard 12V relays that can switch up to 7A load. The BiWire Ultra output relay module is designed to provide a simple means of interfacing. Numato’s 8 Channel Bluetooth Relay Module provides exceptional value for money. Individual relay can be controlled by simple commands. This module is designed to plug into your design seamlessly.

#relay 8 on s = board.write('x80') time.sleep(2) #relays 1 and 2 on s = board.write('x03') time.sleep(2) #all relays off s = board.write('x00') time.sleep(2) board.close()except Exception as e: print ('Unable to get the BitMode of the device.') print (e) board.Request For Quote Wanna Customize? Drop Us A Line!Ĩ Channel Bluetooth Relay Module is great for controlling your devices over the Bluetooth link without any RF design knowledge. Connect the signal terminal IN4IN5 of 8-channel relay to digital port 3,2 of the SunFounder Arduino Mega2560 board, and connect an LED at the output terminal.Pay attention to that there are only two submodules of the 8-channel relay are used in this example, but you can use the 8 submodules freely.
