Raspberry Pi AlaMode

In this section, we will briefly discuss the Raspberry Pi AlaMode's features and its setup. Raspberry Pi AlaMode (as shown in the following figure) is a stackable Arduino development platform developed specifically for the Raspberry Pi. The board, which is released as open source hardware, is priced at about $45 and also includes a real-time clock and a micro SD card slot for data logging.

Prepare for lift off

The attractive feature of the board is that it could be programmed via the Raspberry Pi's UART pins and hence eliminates the need for a USB port. The board could be either powered via the Raspberry Pi or through the Micro B USB port using a wall wart transformer. The product's webpage, http://wyolum.com/projects/alamode/alamode-getting-started/, offers a single step process to start using the board.

Note

The Raspberry Pi AlaMode mode is just one example of the stackable Arduino hardware. There are probably other similar stackable Arduino hardware available in the market. For example, https://www.kickstarter.com/projects/raspitv/raspio-duino-affordable-arduino-programming-on-ras.

Engage thrusters

Once the archive is downloaded from their web page, we extract the contents:
```
tar –xvzf alamode-setup.tar.gz
```
Once the files are extracted, the setup is as follows:
```
sudo ./setup
```
After the installation is complete, the Raspberry Pi a la mode's serial port is enumerated as /dev/ttyS0.

Objective complete – mini debriefing

After the installation is complete, we should have the Raspberry Pi AlaMode mode enumerated and be ready to start programming the hardware add-on board.
