XC3920
Arduino® CompatibleAn all-in-one Arduino compatible board to add dazzling effects to your next project or costume. The round-shaped board features ten mini WS2812 individually addressable RGB LEDs, a motion sensor (accelerometer), temperature sensor (thermistor), light sensor (phototransistor), microphone, buzzer, left and right push-buttons, slide switch, and more to suit a wide variety of applications.
The fourteen power and I/O pads around the edge of the board are alligator clip friendly for prototyping purposes, can be soldered, mounted with metal screws, or sewn into your costume using conductive thread (sold separately). The onboard ATmega32u4 8-bit AVR microcontroller runs your Arduino code, and the eight I/O connections include Serial TX, Serial RX, I2C (SCL and SDA) and four GPIO pins. Program and power the board from USB or 3.3VDC. A battery pack (6V max.) can also be connected to make your project completely portable.
The USB port has HID support to act like a keyboard, mouse, joystick or MIDI, and the eight non-power related pads can be used as capacitive touch applications.
LEDs are compatible with Neopixel and FastLED libraries for example.
