Pololu Basic SPDT Relay Carrier with 5VDC Relay (Partial Kit)

The Pololu Basic SPDT Relay Carrier provides simple control of a single-pole, double-throw (SPDT) switch from low-voltage, low-current control signals. This partial kit includes all components needed – just solder the through-hole parts to complete the build.

Built around an Omron G5LE-14-DC5 relay rated for up to 10A, this carrier can be controlled with signals from 2.5V to 20V, making it compatible with both 3.3V and 5V microcontrollers. Red LEDs on either side of the relay provide visual feedback when activated.

Key Features

• SPDT Configuration – Switch between two circuits with a single relay
• Wide Control Voltage – 2.5V to 20V input range via BSS138K MOSFET
• High Current Capacity – Relay rated up to 10A under most conditions
• Visual Feedback – Dual red LEDs indicate relay activation
• Easy Connection – 5mm terminal blocks for switch wiring
• Mounting Holes – Four holes for #2 or M2 screws
