Product Description

Featuring a 32-bit ARM processor running at 48MHz and boasting 16K of ram, the Tau is far more powerful than your standard Arduino!

Installation

To make the Tau work with the Arduino IDE, open the File menu and select Preferences. Then, in the Additional Boards Manager URLs section, place a comma after the last entry, and add the following link:

http://rabidprototypes.com/arduino/package_rabidprototypes_index.json

Once done, open the boards manager, which can be found on the Tools->Boards menu, scroll down to Rabid Prototypes, select the entry, and hit Install.

Finally go back to Tools->Boards, scroll down to the bottom of the list, and pick the Tau/Firecricket.

Once done, you should be ready to program the board!

Troubleshooting

If you are unable to program the board, first make sure you have the correct board selected on the Boards menu.  Then check that the correct port is selected on the Ports menu.

If that doesn’t work, try double clicking the Reset button on the board.  That forces the bootloader to stay on instead of entering your sketch, which may be stuck in a loop where it is unable to check the USB port for connection attempts from the IDE.
