A Feather board without ambition is a Feather board without FeatherWings! This is the Power 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. Compared to the smaller Relay FeatherWings, this one can handle a beefy 1200 Watts!
Works with all/any of our Feather boards, just wire up the relay control pin to whatever GPIO you like! Using Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top of your Feather board and let the board take flight. Check out our range of Feather boards here.
This Wing has a non-latching type relay. You can switch up to 10A of resistive-load current at 120VAC, 5A at 240VAC. With inductive loads, about half that. Check the datasheet for the relay for the exact switching capacity, as it depends on type of load and voltage type and magnitude. This relay is good for handling fairly large devices, computers, TVs, small appliances, and more.
Each FeatherWing comes with a fully assembled and tested PCB, header you can use to attach to your Feather. By soldering closed the jumper on the underside of the Wing you can select which pin you want to use for the relay control. 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 them safely!

Revision History:
-
As of December 19, 2022 – Adafruit have a version of the Power Relay Featherwing with a larger terminal block, which required moving the relay back in the PCB a bit - you may get either version, they are functionally the same. Adafruit have also updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen
