FeatherWings add specific functionality to your Feather development board. They fit directly on top of your Feather using stacking header pins.
The latching mini relay FeatherWing gives you control over power so you can now turn on and off various devices including lamps, fans, solenoids. In fact, you can switch power for many small appliances that run on up to 250 V ac but you need check the amount of power – 60 W or less.
The latching relay, requires two pins, a SET and UNSET. Instead of keeping the SET pin high, you only have to pulse each pin high for 10 ms to latch the relay open or closed. You need two pins but save power.
In terms of how much power, you can switch up to 2A of resistive current at up to 30 V dc or 40 V ac. At 110 V dc, switch up to 0.3A, at 120 V ac up to 0.5 A, and at 250 V ac you can switch up to 0.6A. Check the datasheet for more details.
A 3-pin terminal block is supplied with this FeatherWing to wire it up with the device you are controlling and some light soldering is required.
A Non-Latching Relay FeatherWing is also available (RS 124-5530) and requires only a single signal pin.

If using with high voltages of more than 24 V, 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 it safely.
