Pololu’s basic 2-channel relay carrier board makes it easy to incorporate two “sugar cube”-style power relays into your electronics project. Integrated MOSFETs allow the relays to be controlled with low-current digital inputs, an indicator LEDs show when the relays are activated. The 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.
