Circuit Playground Express

This board can be programmed with Microsoft MakeCode block-based, Javascript programming, or even Arduino IDE. Then, you can use the same board to try CircuitPython, with the Python interpreter running right on the Express.

The round board has alligator-clip pads around it so you don't have to solder or sew to make it work. You can power it from USB, a AAA battery pack, or with a Lipoly battery. Circuit Playground Express has built-in USB support. Built in USB means you plug it in to program it and it just shows up, no special cable or adapter required. Just program your code into the board then take it on the go!

Circuit Playground Express Features:

• 10 - mini NeoPixels
• 1 - Motion Sensor (LIS3DH triple-axis accelerometer with tap detection, free-fall detection)
• 1 - Temperature Sensor (thermistor)
• 1 - Light Sensor
• 1 - Sound Sensor (MEMS microphone)
• 1 - Mini speaker with class D amplifier
• 2 - Push Buttons
• 1 - Slide Switch
• 1 - Infrared receiver and transmitter
• 8 - alligator-clip friendly input/output pins
• Includes I2C, UART, 8 pins that can do analog inputs, multiple PWM output
• 7 pads can act as capacitive touch inputs and the 1 remaining is a true analog output
• Green "ON" LED so you know its powered
• Red "#13" LED for basic blinking
• Reset button
• ATSAMD21 ARM Cortex M0 Processor, running at 3.3V and 48MHz
• 2 MB of SPI Flash storage, used primarily with CircuitPython to store code and libraries.
• MicroUSB port for programming and debugging
• USB port can act like serial port, keyboard, mouse, joystick or MIDI!

The infrared receiver and transmitter can receive and transmit any remote control codes, as well as send messages between Circuit Playground Expresses. Can also act as a proximity sensor.
