Hardware Interface 

The hardware interface consists of three connectors: 

 

One I/O connector 

 

Two GNSS antenna connectors 

 

All pins on the 44-pin I/O connector are ESD protected. They are tested according to IEC 
61000-4-2 level 4, 8kV contact, 15kV air discharge. 

None of the lines on I/O connector isolated. All voltage levels are referenced with respect 
to the signal ground. 

 

5.1.

 

I/O Connector Pin-out 

The I/O connector is a PCB mounted 44 pin header, male type (Samtec TMM-122-03-S-
D-MW). The pin enumeration is labelled on Figure 3. 

 

 

Figure 3: I/O Connector Pin Enumeration 

  

The I/O connector pin-out functionality is specified in Table 1. 

Note: All signal types marked as TTL refer to standard 3.3V TTL.
