Adafruit HalloWing M0 Express

This is electronics at its most spooky! The Adafruit HalloWing is a skull-shaped ATSAMD21 board packed with features for wearables, badges, cosplay, or props. On the front, a 1.44" 128x128 full-color TFT display comes alive with animations and displays of your choice.

Below the display, four fang-teeth are analog/capacitive touch inputs with alligator-clip holes. The reverse side hosts the ATSAMD21G18 clocked at 48MHz, 256KB FLASH and 32KB RAM, 8MB of SPI Flash, 3-axis accelerometer, light sensor, and a Mono Class-D speaker driver.

Other features include a LiPoly battery port with built-in recharging, USB port for programming, two Feather-compatible header strips, and JST ports for Neopixels and sensors. The device supports Arduino and CircuitPython development environments, making it versatile for any creator.

The extra 8MB of SPI Flash is perfect for sound effects, allowing up to 3 minutes of WAV files. With JST-PH plugs on each side, connect external devices easily. The Hallowing comes fully assembled with a UF2 bootloader for easy code updates.
