With this part, you will be able to remotely turn on, turn off and restart your computer!

  • x4 MOSFET relays OMRON G3VM-61A1 or OMRON G3VM-61AY1.
    Don't use random relay modules or random optocouplers! Some of these may not be sensitive enough for the Raspberry Pi, some others may be low-level controlled. Either use relays that are activated by a high logic level, or follow the design provided and buy an OMRON. See details here.
  • x4 390 Ohm resistors (see here for alternatives).
  • 2x 4.7 kOhm resistors.
  • x10+ dupont wires male-male.
  • x1 a breadboard.
  • various wires for the breadboard.
