Feather is a perfect form factor for handheld gaming, to put inside wearables and props.
Here are FeatherWings which may be added to a Feather to help your creative side.
Add a joystick and buttons with the cute Joy FeatherWing. This FeatherWing has a 2-axis joystick and 5 momentary buttons (4 large and 1 small) so you can turn your feather board into a tiny game controller. This wing communicates with your host microcontroller over I2C so it's easy to use and doesn't take up any of your precious analog or digital pins. There is also an optional interrupt pin that can alert your feather when a button has been pressed or released to free up processor time for other tasks.
The Prop-Maker FeatherWing will unlock the prop-maker inside all of us, with tons of stuff packed in to make sabers & swords, props, toys, cosplay pieces, and more.
We looked at hundreds of prop builds, and thought about what would make for a great low-cost (but well-designed) add-on for our Feather boards. Here's what we came up with:
- Snap-in NeoPixel port - With a 3-pin JST connector, you can plug in one of our JST-wired NeoPixel strips directly, or use a 3-pin JST connector to wire up your favorite shape of addressable NeoPixel LEDs. This port provides high current drive from either the Feather Lipoly or USB port, whichever is higher. A level shifter gives you a clean voltage signal to reduce glitchiness no matter what chip you're using
- 3W RGB LED drivers - 3 high current MOSFETs will let you connect a 3W RGB LED for powerful eye-blasting glory. For most Feathers, the 3 pins are PWM capable so you can generate any color you like. Available as pin breakouts plus strain-relief holes
- Triple-Axis Accelerometer with Tap Detection - The LIS3DH is our favorite accelerometer, you can use this for detection motion, tilt or taps. Here's an example of a light saber that makes sounds when swung or hit. We have code for this chip in both Arduino and CircuitPython.
- Class D Audio Amplifier - Drive a 8Ω 1 Watt speaker or 4Ω 3W speaker for sound effects. Plug and play with our cute and slim oval speaker, or connect a picoblade cable for your favorite speaker. For use only with Feathers that have analog audio out such as the Feather M0 Express and M4 series.
- Low power mode! The power system for the RGB LED, NeoPixels and speaker amplifier can be controlled by a pin to cut power to them, so you have lower power usage when the prop is in sleep or off mode (but can wake up fast by listening to the button press or accelerometer data). When the power pin is set low, the current draw for just the wing is under 1mA and no there's current draw from any attached NeoPixels - normally they're about 1mA even when not lit.
- Breakouts plus strain-relief hole for the enable pin and ground (for a mechanical switch that will power down the whole board)
- Breakouts plus strain-relief holes for an external switch pin and ground (for a mechanical mode button)
Please note: A few of the onboard hardware elements use PWM and analog output so we recommend the Feather M0 Express or Feather M4 series, they'll work best with this wing and let you make the most of it.
