{"title":"Adafruit Mini Relay FeatherWing - Latching","handle":"adafruit-mini-relay-featherwing-latching","url":"/products/adafruit-mini-relay-featherwing-latching","description":"The Adafruit 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.\n\nThis is the latching version, which uses two control pins (SET and UNSET). A brief 10 ms pulse on either pin latches the relay open or closed, saving power between switching events. The relay retains its last state even if power is lost. Attach it to your Feather using Feather Stacking Headers.\n\nKey Features\n\n\nLatching Relay – Pulse SET or UNSET for 10 ms to toggle; retains state without power\n\nFlexible 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)\n\nTwo-Pin Control – Dedicated SET and UNSET GPIO pins for reliable latching operation\n\nScrew Terminal Block – 3-pin terminal included for easy load wiring\n\nFeather Compatible – Works with any Feather board via standard header connection\n\nPre-Assembled PCB – Light soldering required to attach the included header\n\n\n\nWarning: If using with voltages above 24 V, exercise caution. High-voltage wiring requires experience and should only be performed by qualified individuals following appropriate safety guidelines.\n\n\nIdeal For\n\nHome automation and IoT switching\nLow-power applications where the relay must hold state without continuous current\nControlling lamps, fans, solenoids, and small appliances (up to 60 W)\nBattery-powered projects where power conservation matters\n\n\nPackage Contents\n\n1× Latching Mini Relay FeatherWing (assembled and tested)\n1× 3-pin terminal block\n1× Header strip (requires soldering)\n\n\n\nNote: For higher-power loads up to 1200 W (10 A), see the Power Relay FeatherWing. Terminal block colour may vary (blue or black).\n\n\nResources\n\nMini Relay FeatherWing Learn Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11332,"title":"Default Title","sku":"AF-2923","price":16.5,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
