Pololu Basic SPDT Relay Carrier for "Sugar Cube" Relays

Pololu’s basic relay carrier board makes it easy to incorporate a “sugar cube”-style power relay into your electronics project. An integrated MOSFET allows the relay to be controlled with a low-current digital input, and a pair of indicator LEDs show when the relay is activated. The three control pins have a 0.1" spacing compatible with standard solderless breadboards and servo cables, and the switch pins are available for use with 5mm-pitch terminal blocks or 0.2"-spaced pins.
