Please refer to the schematic diagram for the configuration of this board. Individual relays can be controlled by simple commands. These handy relay modules provide the easiest way to use your DuinoTECH to switch real world devices. This module plugs in to your design seamlessly. The 8-Channel Relay Driver Shield makes it simple and convenient to drive up to 8 loads such as 12V relays from just 2 pins of your Arduino compatible board or other microcontroller. UnSubscribe. The double FR–4 circuit board … 8 Channel relay boards have the capability to daisy chain units in a string - connected to one control method (RS-232, USB, etc.) 8 Channel Relay Board is a simple and convenient way to interface 8 relays for switching application in your project. The WiFi relay board is with 8 SPDT relays rated up to 7A each. Anyway, once you get it installed, you can just call it from the command line and it will list your relay_ids in some format with suffixes that look like _1 through _8. but in this bord is old . Read about company. You can control devices 230V/120V (up to 8) directly with one such relay unit. This board has eight on-board Solid State Relays which can switch up to 3A. Sold by Luoyuu and ships from Amazon Fulfillment. The Arduino Bluetooth Relay 8 Channels App supports controlling an 8-channel relay module via Bluetooth (HC-05, HC-06, HC-07 ect.) You can use any of the output channels independently, so simply leave any unused channels disconnected.
