This basic 2-channel relay carrier board makes it easy to incorporate two single-pole, double-throw (SPDT) “sugar cube”-style power relays into your electronics project. Integrated MOSFETs allows the relays to be controlled with low-current digital inputs, and indicator LEDs show when the relays are activated. The four control pins are accessible via a top-entry JST SH-style connector that works with our selection of 4-pin JST SH-style cables, and the switch pins are available for use with 5mm-pitch terminal blocks or 0.2″-spaced pins. Note: Relays not included.
