A Feather board without ambition is a Feather board without FeatherWings! This is the Non-Latching Mini Relay FeatherWing. It gives you power to control, and control over power. 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.
Using Adafruit's Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top of your Feather board and let the board take flight.
The are two 'flavors' of these FeatherWings, this is the simple Non-Latching relay. This Wing has a single Set pin. Normally, the relay'sCOM pin is connected mechanically to the NC pin and the NO pin is disconnected.
When the SET pin is pulled high, the relay switches and the internal switch changes so that the COM pin is mechanically connected to the NO pin and NC is then 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'.
Each 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.
Please note: If using with high voltages (> 24V) use care and common sense! High voltages require experience, and are only for use by engineers who are comfortable with guidelines and know how to use safely!
Also: the terminal blocks included with your product may be blue or black.
