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
Using our Feather Stacking Headers or Feather Female Headers you can
connect a FeatherWing on top of your Feather board and let the board
The are two 'flavors' of these FeatherWings, this is the simple
Non-Latching relay. This Wing has a single Set pin. Normally, the
relay's COM pin is connected mechanically to the NC pin and the NO pin
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'.
Now, you might be thinking "wow I really don't want to waste 50mA of
current, that will really sink my battery life!". OK good news, we
have another type of FeatherWing, the Latching FeatherWing. You need
two pins but save power. Note, if power is lost, the relay will stay
in the last setting.
Both FeatherWings use the same family of relay. You 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.
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
