The Adafruit Feather series gives you lots of options for a small, portable, rechargeable microcontroller board. Perfect for fitting into your next prop build! This 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.
This version of the FeatherWing has plain headers soldered in, so it's easy to plug into our Feathers.
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:
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 Expressor Feather M4 or ESP32 series, they'll work best with this wing and let you make the most of it. For example:
Feather 32u4 and 328p do not have PWMs for all the RGB LED pins, and no analog audio output support
Feather nRF52, and ESP8266 do have PWMs on all the RGB LED pins but no analog audio output support
Feather M0 basic boards only have audio output support in Arduino, not CircuitPython.
