These logic level inputs are the primary (A) and secondary (B) serial port receive 
lines (data input to the module). This output meets the input/output pin threshold 
specifications (see 

.) The baud rate 

for the two ports is under software control.

These logic level outputs are the primary (A) and secondary (B) serial port transmit 
lines (data moving away from the module). This output meets the input/output pin 
threshold specifications (see 

The baud rate for the two ports is under firmware control.

There are 8 reserved pins on the Copernicus GPS Receiver. For the recommended pin 
connections for these reserved pins, see
