Relay for Raspberry Pi or Arduino 1-Channel 5V Relay Module 250V

A "normal" style relay to switch a single "data" line to turn on/off.   Perfect for RaspberryPi or Aduino projects. You need 5v to power the relay coil. The input (IN) requires just a few milliamps at anywhere between 2.5v and 12v. You can even use the same voltage you are powering the coil from. Features: ·         Lo

Using a raspberry pi to control this 5v relay. Do I need a power source running into the relay? Or is my pi enough? : r/AskElectronics

This 1-channel 5V control Single-Pole Double-Throw (SPDT) AC power relay board can be controlled directly via a microcontroller and switch up to 10 amperes at 250 VAC. Inputs are isolated to protect any delicate control circuitry. The default state of the relay when the power is off for COMM (power) to be connected to NC (Normally Closed). This is the equivalent of setting the relay board IN pin to HIGH (has +5v sent to it).
