Adafruit NeoTrellis M4 | DigiKey Daily
Adafruit’s NeoTrellis M4 is an Arduino IDE, Circuit Python starter kit. It’s powered by the SAMD51 32-bit Cortex M4. For memory, it has 512 kilobytes of Flash, 192 kilobytes of RAM, and an 8-megabyte Flash chip for custom files and audio clips. There's a 4-by-8 grid of elastomer button pads with a NeoPixel in the center of each one. Users can read any or all button presses simultaneously thanks to the fully diode'd matrix, and also set each button color to any of 24-bit colors. For audio, the SAMD51 provides dual DACs, and they’re connected to the left and right on a standard headphone jack. And for more interactivity, an included precision triple-axis accelerometer provides sensor information on tilt, motion, or tapping.
