The Adafruit Non-Latching Mini Relay FeatherWing lets you control mains-powered devices and small appliances using any Feather microcontroller. Switch lamps, fans, solenoids, and other loads rated up to 250 VAC or DC — all from a compact FeatherWing form factor.
This is the non-latching version, which uses a single control pin. Pull the SET pin high to activate the relay (a red LED indicates when it's on). The relay draws approximately 50 mA while energised and returns to its default open state if power is lost. Attach it to your Feather using Feather Stacking Headers.
Key Features
- Non-Latching Relay – Single-pin control; COM connects to NO when SET is high, returns to NC when released
- Flexible Switching – Up to 2 A at 30 VDC / 40 VAC, 0.5 A at 120 VAC, or 0.6 A at 250 VAC (60 W max recommended)
- Status LED – Red LED lights when the relay is active
- Simple Control – Only one GPIO pin required to operate
- Screw Terminal Block – 3-pin terminal (COM, NC, NO) included for easy load wiring
- Feather Compatible – Works with any Feather board via standard header connection
- Pre-Assembled PCB – Light soldering required to attach the included header
Ideal For
- Home automation and IoT switching
- Controlling lamps, fans, solenoids, and small appliances (up to 60 W)
- Projects where simple on/off control is sufficient
- Prototyping relay-controlled circuits with Feather boards
Package Contents
- 1× Non-Latching Mini Relay FeatherWing (assembled and tested)
- 1× 3-pin terminal block
- 1× Header strip (requires soldering)
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- FeatherWing
- A FeatherWing is an add-on board made to plug into the Feather microcontroller board layout. Knowing a product is a FeatherWing helps you check whether it will physically and electrically fit your Feather-style mainboard.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- Terminal block
- A connector used to join wires together in a neat, removable, or serviceable way. For this product, it helps split one power input into several outputs without soldering.
