We've purchased a couple of Tessel gps-a2235h modules for evaluation. We aren't currently using Teasel but rather just trying to talk to the modules over the serial port. I was unable to locate the schematic for the module and am having trouble determining what the default baud rate is. Currently the baud rate config pins I2C_DIO and I2C_CLK appear to be floating. Are these pins connected to any of the pins on the breakout connector?
