4 Electrical Interfaces
The following subsections contain information for the electrical interfaces of the Tile.
4.1 User Host Device
The user host device provides the following connections to the Tile:
● DC power supply input: 3.3V, 1000 mA peak
● Serial data interface
● Satellite signal (Use either the provided U.FL connector labeled SAT
or
Pin 18. See
section 5.3 - RF Trace Layout Design for more information)
● GPS signal (Use either the provided U.FL connector labeled GPS
or
Pin 8)
● GPIO_1 (optional)
4.2 Tile Pin Allocation
The pin numbering scheme of the Tile is shown in
Figure 4
. The module pins allow soldering
onto a printed circuit board (PCB) using standard reflow soldering techniques. The pin function
assignment is given in
Tables 6
and
7
. Multiple supply grounds are provided and all supply and
supply grounds are required to be connected to the power supply in order to limit the current on
any one pin. Multiple signal grounds are provided to reduce cross-talk. Pins 13 and 14 are
intentionally left empty, and must be left unconnected.
