The Pololu basic relay carrier makes it easy to control a single-pole, double-throw (SPDT) power relay that has the common “sugar cube” pinout and footprint. This product is just the carrier board PCB assembled with all of its surface mount components, including a MOSFET for controlling the relay, indicator LEDs, and a flyback diode; it does not include a relay or connectors. This board is also available with 5 V and 12 V power relays.

The Pololu basic 2-channel relay carrier modules make it easy to control two single-pole, double-throw (SPDT) power relays that have the common “sugar cube” pinout and footprint.

The carrier board routes the three relay control pins to 0.1″-spaced pins compatible with standard solderless breadboads and female servo cable connectors. The relay switch pins are routed to a set of large pads intended for use with a 3-pin 5mm-pitch terminal block and a set of smaller pads with a 0.2″ pitch, making them compatible with 0.1″ perfboards. The carrier board has four mounting holes that work with M2 / M3 screws.
