4 Electrical Interfaces
The following subsections contain information for the electrical interfaces of the Tile. The RF
interfaces are covered in section 5.
4.1 User Connector
The user connector provides the following required connections to the Tile:
• DC power supply input, 3.3V, 1000 mA peak
• Serial data interface
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 5 and 6. 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 have no function.
