We have recently purchased an Adafruit Circuit Playground. I was really excited to finally able to hold it as it is a small board packing with a lot of features. Some of the features I have not used yet.
Here are the list of features of the Adafruit Circuit Playground.
Board Dimension: 50.6mm (2.0 inches) in diameter
Weight: 8.5 grams
ATmega32u4 Processor (3.3V, 8MHz)
MicroUSB for programming and debugging with Arduino IDE and power
USB port can act like serial port, keyboard, mouse, joystick or MIDI
2 pin JST port for Power (3-6V)
10 mini NeoPixels (each can display any color)
1 Motion Sensor (LIS3DH triple-axis accelerometer with tap detection, free-fall detection)
I had a hard time imagining how the microSD Card Breakout Board would fit physically into my project so I decided to create this post just in case you want to see close up photos of the breakout board.
