These are high quality sealed Single Pole - Double Through (SPDT) relays. This relay's coil is rated for 5V. The nominal operating current is 72mA so it will need additional circuity to close the relay with a microcontroller like an Arduino or SBC such as a Raspberry Pi or BeagleBone Black.
Powered by the ULN2003 high current driver, this module gives you easy control of up to 7 relays using TTL logic from an Arduino, Beagle Bone, or Raspberry Pi. 5V, 12V, and 24V relay options.
RELAY GENERAL PURPOSE DPDT 8A 5V
The power distribution board features a 5V 5A regulator, and a 12V 2.2A regulator to supply your next project with power safely, and efficiently.
