I have the verdex with netwifimicrosd and robostix.  Unless I attempt to redesign the tweener board to fit my stack I think my only option to add an RS232 interface is via the 24-pin flex connector.   But I also want to add USB.  Has anyone made a board using the 24-pin flex connector that has multiple USB or RS232 interfaces?  I am not an electrical engineer so developing my own board seems to quite a daunting task.  If you have a solution or an idea that might work then let me know.
