10-18-2014 - I've created version 14 of the TeensyNet Board. I've added the ability to use one of the Serial Ports of the Teensy3.1 as an external debug monitor using a USB-to-TTL RS232 cable. The second I2C line has been brought out to terminalblocks using 3v3 to 5V level converters. I've also added activity LEDs and test points.
