What is it

What is it?

Open source

Open Source

  • Open Source Hardware

  • Open Source Bootloader

  • Open Source Development Kit

  • Community Driven Support



  • I/O Board - main microcontroller

  • Shield - add-on boards

  • Sketch - the program

  • Sensor - components (thermistors, etc.)

  • Modules - serial data (GPS module, etc.)

What do these do

What do these do?

Digital IO (LEDs, switches)

Analog IO (resistive sensor data)

Serial Connection (Sensors, GPS, etc)

Program from your computer

Your limit is only your creativity!
