Sorry, I mistyped the specs: its 20x4.  It might be enough room to allow you to define 3 or 4 "soft keys".  ie., have 3 or 4 buttons right underneath the display and change the bottom line of the display according to context.

That’s close to what I am using now... But 16x2 4 bit one, then using a $1.25 MCP23017 as a I2C fanout...

Hey Guys,

May of you know I have been working to get FreeSWITCH crammed on to the RaspberryPi. And a few of you have noticed where I have been blogging about it at http://www.switchpi.org/ well its come time to ask for a little help...

If you have an EE background and have recently sent boards sent off to a short run proto fab and want to assist in a little refinement of the PCB, I think its time to start heading down that road. Please contact me off list with how you can help.

Where am I currently? A) FreeSWITCH Building cleaning on Raspbian (I’ll be making an image with FS precompiled and installed shortly), B) breadboard hardware working with Python and limited C sources.

Eagle Files and Source code is on Github (Linked off the blog for easy reference)
