Updated! The guide to our popular Prop Maker FeatherWing has been updated with example code for CircuitPython.
What makes the Prop Maker special? I’m glad you asked:
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)
Consider the Prop Maker FeatherWing and an Adafruit Feather M0 or M4 board for your next prop project for a small, economical and fun build!
