This low-cost Prop Shield is meant for making light and sound effects on small handheld props and wearable costumes.
- Audio Amplifier - Clear quality audio output to a small speaker.
- Fast LED Driver - Drive APA102 / Dotstar LEDs for colorful lighting with rapid response.
- Flash Memory - 8 Mbyte storage for images, sound clips, and data logging.
This shield features a 2 watt audio amp, high speed 5V buffers for driving APA102 LEDs, and an 8 Mbyte flash memory for images, sound clips, or data logging. It's approximately the size of a Teensy, just slightly longer to allow space for mounting holes and connections for power, speaker, and LEDs.
This lower cost Prop Shield is identical to the standard Prop Shield, except the motion sensors are removed.
Please refer to the standard Prop Shield page for all details.
Jargon buster
Plain-language definitions for the technical terms used above.
- Flash memory
- Non-volatile memory that keeps stored data even when power is removed. In this sensor, it matters because enrolled fingerprint templates can remain saved after the project is turned off.
- LED driver
- An LED driver is a control chip or circuit that supplies and switches power to LEDs. For a display board, it reduces the number of microcontroller pins needed and handles tasks like lighting the right segments and adjusting brightness.
- 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.
