It combines the RP2040 microcontroller with a prop-making toolkit — I2S audio amplifier, NeoPixel driver with level shifting, accelerometer, and servo header — with screw terminal connections for minimal or no soldering.\n\nPowered by CircuitPython or Arduino, this board boots instantly and can drive LED strips, play sound effects through a speaker, detect motion and taps, and control a servo — everything you need for an interactive prop in one compact Feather.\n\nKey Features\n\n\nRP2040 Processor – Dual-core Cortex M0+ at 133 MHz with 264 KB RAM and 8 MB QSPI flash\n\nMAX98357 I2S Audio Amplifier – 3 W Class D amplifier for driving 4–8 Ω speakers via screw terminals\n\nNeoPixel Port with Level Shifter – 5 V level-shifted output on screw terminals with power cut-off transistor for low-power sleep\n\nLIS3DH Triple-Axis Accelerometer – Motion, tilt, and tap detection for interactive responses\n\nServo Header – Standard 3-pin 0.1\" header for hobby servos\n\nExtra Button/Output Pin – Additional screw terminal for activation button or digital output\n\nLow Power Mode – Pin-controlled power cut to NeoPixels and amplifier for sleep/standby\n\nSTEMMA QT Connector – Plug-and-play I2C for additional sensors and peripherals\n\nUSB Type C – For programming, serial debugging, and power\n\nLiPo Battery Support – Built-in 200 mA+ charger with automatic USB/battery switching\n\n\nAlso Consider\n\n\nFeather RP2040 – Standard RP2040 Feather without prop-making hardware\n\n\nIdeal For\n\nLightsabers and illuminated swords with motion-reactive sound\nCosplay props with lights, sound, and motion detection\nAnimatronics with servo control and audio\nInteractive toys and wearable electronics\n\n\nPackage Contents\n\n1× Adafruit RP2040 Prop-Maker Feather (assembled and tested)\n1× Header strip (soldering required for breadboard use)\n\n\n\nNote: Speaker, NeoPixel strip, servo, and LiPo battery are sold separately. The screw terminals allow solderless connection for most prop builds.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1584,"title":"Default Title","sku":"AF-5768","price":41.23,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":101,"option1":"Default Title"}]}
