Stackable to 8 layers, the 4-RELAYS card can control loads of up to 10A and 250V.  All relays have N.O. and N.C. contacts brought to pluggable terminal block.  Up to 8 cards can be staked on top of one Raspberry Pi for a total of 32 relays.  Open Source design including Schematics.

FEATURES:

  • Four on-board relays with status LEDs
  • Eight layer stackable to 64 relays
  • Switch loads of up to 10A and 250V
  • Pluggable terminal blocks
  • Command line, Python drivers
  • Package includes mating connectors, 18mm stand-offs, screws and nuts

The 4-RELAYS cards share the I2C bus using only two of the Raspberry Pi’s GPIO pins to manage all eight cards.  This feature leaves the remaining 24 GPIOs available for the user.
