  4 Channel relay board for your Arduino or Raspberry PI - 12V

  A general purpose 4 SPDT channel relay board (power supply 12VDC) for switching high-current electrical loads (both AC and DC) such as motors, lights, pumps, contactors and more.  With this relay board, any logic-level signal from 3V up to 30V can be used to activate a relay (it may be controlled direclty by microcontroller TTL logic as well). It can be used successfully for example with PIC,AVR,ARM microcontroller, Raspberry PI, Arduino outputs and other.
