The Adafruit Non-Latching Mini Relay FeatherWing lets you control mains-powered devices and small appliances using any Feather microcontroller. Switch lamps, fans, solenoids, and other loads rated up to 250 VAC or DC — all from a compact FeatherWing form factor.

This is the non-latching version, which uses a single control pin. Pull the SET pin high to activate the relay (a red LED indicates when it's on). The relay draws approximately 50 mA while energised and returns to its default open state if power is lost. Attach it to your Feather using Feather Stacking Headers.

Key Features

• Non-Latching Relay – Single-pin control; COM connects to NO when SET is high, returns to NC when released
• Flexible Switching – Up to 2 A at 30 VDC / 40 VAC, 0.5 A at 120 VAC, or 0.6 A at 250 VAC (60 W max recommended)
• Status LED – Red LED lights when the relay is active
• Simple Control – Only one GPIO pin required to operate
• Screw Terminal Block – 3-pin terminal (COM, NC, NO) included for easy load wiring
• Feather Compatible – Works with any Feather board via standard header connection
• Pre-Assembled PCB – Light soldering required to attach the included header

Ideal For

• Home automation and IoT switching
• Controlling lamps, fans, solenoids, and small appliances (up to 60 W)
• Projects where simple on/off control is sufficient
• Prototyping relay-controlled circuits with Feather boards
