Put simply, you can now turn on and off lamps, fans, solenoids, and other small appliances that run on up to 250VAC or DC power using any Feather board.\u003c\/p\u003e\n\u003cp\u003eUsing our \u003ca href=\"\/en-eu\/products\/feather-stacking-headers-12-pin-and-16-pin-female-headers\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eFeather Stacking Headers\u003c\/a\u003e or \u003ca href=\"\/en-eu\/products\/feather-header-kit-12-pin-and-16-pin-female-header-set\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eFeather Female Headers\u003c\/a\u003e you can connect a FeatherWing on top of your Feather board and let the board take flight. \u003ca href=\"\/en-eu\/search?type=product\u0026amp;q=feather\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCheck out our range of Feather boards here\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eThe are two 'flavors' of these FeatherWings.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe \u003cstrong\u003eLatching\u003c\/strong\u003e relay requires two pins, a \u003cstrong\u003eSET\u003c\/strong\u003e and \u003cstrong\u003eUNSET\u003c\/strong\u003e and instead of keeping the SET pin high, you only have to pulse each pin high for 10ms to latch the relay open or closed. You need two pins but save power. Note, if power is lost, the relay will stay in the last setting.\u003c\/li\u003e\n\u003cli\u003eThe \u003cstrong\u003eNon-Latching\u003c\/strong\u003e relay has a single Set pin. Normally, the relay's COM pin is connected mechanically to the NC pin and the NO pin is disconnected. When the relay is active, a red LED is lit, and about 50mA of current is used to keep the coil switched on. Note, if power is lost, the relay will go back 'open'.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eBoth FeatherWings use the same family of relay. \u003c\/span\u003eYou can switch up to 2A of resistive current at 30VDC or ~40VAC or lower. At 110VDC you can switch up to 0.3A, at 120VAC up to 0.5A, and at 250VAC you can switch up to 0.6A. Check the datasheet for the relay for the exact switching capacity, and of course, for reactive\/inductive loads you will need to derate. This isn't a relay you can use to turn on and off your washer\/dryer, stick to 60W or less.\u003c\/p\u003e\n\u003cp\u003eEach FeatherWing comes with a fully assembled and tested PCB, header you can use to attach to your feather. You also get a 3-pin terminal block you can use to wire up whatever you are going to be relay-controlling. Some light soldering is required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note\u003c\/strong\u003e: If using with high voltages (\u0026gt; 24V) use care and common sense!
