Putting it together

ProtoCentral Kalam v3 is our newest IOT platform based on the ESP8266 Wi-Fi SoC. It's easy-to-use, low cost and easily scalable.

The new plug-to-play feature allows you to plug-in "modules" to the basic Kalam v3 board to add more functionality such as sensors and actuators.

This documents guides you through the various steps required to put the basic blocks togther and get your first program up and running.

Step 1 - Connecting the boards

Kalam Assembly-Step 1

Take the Kalam v3 main board and the GPIO cap provided in the kit. On the reverse side of each board, you will find a white 31-pin connector that mates with the other. Gently put it together and then press firmly to get a good fit. The connectors only go in one way, so make sure to align them properly. The connectors should align up with each other as shown in the below picture.

Step 2 - Connect the battery

If you have purchased Kalam as a kit and you have a Li-Ion battery included, connect the battery to the white JST connector on the board as shown below.

Kalam Assembly-Step 2

This connector will also go in only one way. Please note the direction in which it is to be inserted.

If you purchased the Kalam board separately and a battery was not included, you can use it with any 3.7V Li-Ion/Li-Poly battery with a JST connector. Ensure that the connector has the proper polarity before connecting any external battery pack.

Step 3 - Plugging it into a breadboard (optional)

If you have a breadboard, you can now directly plug in the entire assembly into a standard breadboard and it should now be ready for prototyping

Step 4 - Setting up Arduino for Kalam

Kalam is powered by the Sparkfun's board support file.The first thing you will need to do is to download the latest release of the Arduino IDE. You will need to be using version 1.6.4 or higher. After you have downloaded and installed v1.6.4, you will need to start the IDE and navigate to the Preferences menu. Sparkfun's JSON url for ESP8266 board is -



You're now ready to start using the Kalam with the Arduino IDE !

Once you have set-up this, you now proceed to try out your first IoT experiment to post some data to the ThingSpeak platform.
