Adafruit has today announced a new addition to their range of FeatherWing add-on boards with the availability of two FeatherWing relays that offer both latching and non-latching and are now available to purchase directly from the online Adafruit store.
The new addition to the ever growing range of development boardsProvides an easy way to control power allowing you to easily turn on devices and small appliances that run on up to 250VAC or DC power using any Feather board.
Adafruit explains more :
The are two ‘flavors’ of these FeatherWings, this is the Latching relay. This one requires two pins, a SET and UNSET 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.
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.
