We offer several expansion modules for the Propeller Platform, but what if you want to make your own?

The Propeller Platform is designed to be easily expandable with all 32 I/O pins available with 5V & 3.3V power, here are 3 easy ways to expand it;

Protoboard / perfboard / veroboard / stripboard

There are several varieties of prototyping circuit boards, but all of them will work with the Propeller Platform's .1" spacing, just add pin headers and drop that board into the pin sockets of the Propeller Platform.

Breadboard

Two ways to hookup to a breadboard;

1 – Hookup wire

Use hookup wire to connect the female headers on the Propeller Platform to a breadboard;

This works fairly well, although it can be a pain moving your project unless you have something that supports both the breadboard and Propeller Platform. 

2 – Headers

Solder pin headers to the inside row of the Propeller Platform pointing down;

Then, you can directly connect the Propeller Platform to a breadboard;

I'm using a small breadboard here, but if you use a larger board, you can connect all 32 I/O. I prefer this method because it's a more robust connection and you can move your project all in one piece. The only downside is the pin headers are a permanent installation.

Design your own circuit boards

Want something more professional looking & robust? Making your own circuit board is the best way to go. The Propeller Platform is 2.5" high, the same size as ExpressPCB's Miniboard service, and you can get 3.8" x 2.5" board for $50. We have templates for ExpressPCB, Eagle, and Diptrace here.

Also, if you plan on offering your add on module to other users, let us know and we'll help you tell everyone about it – info@gadgetgangster.com.
