Software Installation
Note: The Ethernet Arduino example assumes you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review the following tutorials.
Processor Arduino Board Definitions and Driver
Make sure you go through the Hookup Guide for your chosen Processor Board to install the Arduino board definitions and any necessary drivers:

Add the processing power and versatility of the Teensy to your MicroMod project following this guide for the SparkFun MicroMod Teensy Processor.
Note on Artemis and nRF52840 Processors: Currently the Artemis and nRF52840 do not have built in Ethernet libraries in their Arduino cores. An external Arduino Ethernet library may work but at this time Ethernet is not supported on those Processors. We will update the tutorial in the future if Ethernet support is added to these cores.
Main Board Example - Pin Connection Table
The table below helps show what pins the Function Board connects to depending on the slot it is connected to on a Main Board (Note: The Single Main Board connection is Slot 0):
| AUDIO | UART | GPIO/BUS | I2C | SDIO | SPI0 | Dedicated |
