The Pololu Basic SPDT Relay Carrier for "Sugar Cube" Relays facilitates the integration of a "sugar cube"-style power relay into electronic projects. It features an integrated MOSFET for low-current digital input control and dual indicator LEDs to signal relay activation. The board is designed for compatibility with standard solderless breadboards and servo cables, with switch pins adaptable for terminal blocks or perfboards. The compact layout includes a Zener diode for efficient current decay and adheres to electrical routing clearance rules for relay switch nodes.
