This is a 2-channel HIGH-level trigger relay, apply to Arduino and Raspberry Pi. Relays are suitable for driving high power electronic devices such as lights, electric fans and air condition.
You can just uplug the headers to disconnect the device with the module after the experiment and don’t need to unscrew the wires in the socket. Kindly reminder:Be careful with your fingers when unplugging the headers.
There are two soldering points for 5V and GND at the two ends of the module. So you can just weld other relay modules to it and have a relay module of more channels, signals of which are independent of each other.
For more information, refer to the following linkage http://wiki.sunfounder.cc/index.php?title=2-Channel_High_Level_Trigger_Relay
- 5V 2-Channel Relay interface board and each one needs 15-20mA Driver Current

6. Customs & Import fees
Such as the products you buy on our site - can't simply be shipped freely from country to country. When goods are imported into a different country or customs territory, there is a charge called Customs Duty that must apply. This is charged by the local customs authority where the goods are being imported into.
If Customs Duty is payable to your territory, you'll be responsible for paying it to the authorities, so SunFounder isn't involved in this process. Whether Customs Duty is payable, and by how much, depends on a whole lot of different things. For example, many countries have a 'low value threshold' below which they do not charge any Customs Duty.
If you do have to pay Customs Duty though, the amount payable is usually calculated based on the value of the goods and the type of goods being imported.
AND IF I DON'T PAY THE CUSTOMS DUTY?
If, for whatever reason, you refuse the customs fee and the parcel is returned back to us. If you're still unsure on whether you'll be subject to customs fees, we recommend contacting your local customs office for more info before placing your order!
