AlaMode is a stackable arduino clone that empowers a Raspberry Pi with the ability to add arduino shields to it. It is an open source platform and easy to use.
AlaMode comes in a package like the one shown below:
The datasheet for the AlaMode is available here.
It is possible to program the platform via the UART pins of the Raspberry Pi’s GPIO. The Wyolum webpage has provided clear instructions to get started with the hardware.
The board can be driven by the power supply via the Raspberry Pi or a wall wart. The jumper is located here as shown below:
I got the typical arduino LED example working using the AlaMode.
