The jumper labeled VIN/VSYS allows you to remove the VSYS line from

powering the Arduino block. This is handy if you need to isolate the Arduino

block’s power source from the Edison. In this case, you’ll need to supply

power (3.3-12V) externally via the “VIN” pin.

Using the Arduino Block

To use the Arduino Block, attach it to either an Edison or add it to a stack of

other SparkFun Block’s.

In order to supply power to your Edison, you’ll need at least one additon

Block in your stack. You can use a Base Block or Battery Block, for

example.

Programming the Arduino

The Arduino on the Arduino Block can be programmed while it’s either on

or off the Edison. Depending on your application, though, it’s recommended

that you load code on the Arduino while it’s disconnected from your Edison

stack, before adding it to the rest of the system.

If you’ve ever uploaded an Arduino sketch to an Arduino Pro or Pro Mini,

you’re already familiar with uploading code to the Arduino block. Connect a

3.3V FTDI Basic to the 6-pin FTDI header on the board.

In Arduino (the non-Edison version of Arduino!), select “Arduino Pro or Pro

Mini 3.3V/8MHz” from the Tools > Board menu. If you’re using the latest

release of Arduino (1.6 or later), first select Arduino Pro or Pro Mini from

the “Board” menu.
