The SparkFun Qwiic FeatherWing (Shield for Thing Plus) provides an easy-to-assemble way to add the STEMMA QT / Qwiic connect ecosystem to any development board with Feather/Thing Plus Footprint. It connects the I2C bus (GND, 3.3V, SDA, and SCL) on your Feather to four SparkFun Qwiic / Stemma QT connectors. The plug-n-play ecosystem allows for easy daisy chaining so, as long as your devices are on different addresses, you can connect as many Qwiic & Stemma QT devices as you'd like.
This jumper is a little different than normal I2C pull up jumpers as it is open by default. The jumper only needs to be closed if your I2C device does not have pull up resistors. All Adafruit I2C Stemma QT breakouts come with pull up resistors on them so if you are using a Qwiic or Stemma QT I2C device from Sparkfun or Adafruit, you don't need to close the jumper pads.
All that is needed to get started is to solder your chosen headers to the PCB and, if necessary, to your Feather board. Take care to match the markings on the Qwiic Shield to the appropriate pins on your Feather to avoid shorting anything out and possibly damaging your boards.
Features:
- Feather and Thing Plus Compatible
- 4 x STEMMA QT / Qwiic Connection Ports on I2C port + 3.3V + ground power
- I2C Jumper to add I2C pullup resistors
Note: This board does not come with headers, it's just the assembled PCB. But we have plenty o' options in the shop!
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.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- 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.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
- Thing Plus
- Thing Plus is SparkFun’s development-board form factor with a small rectangular layout and connections suited to wireless and battery-powered projects. It matters because boards and accessories in the same form factor are easier to mount, wire, and swap between projects.
