Production information
2.2 Minimal design
This is a minimal setup for a GNSS receiver with a LEA-M8S and LEA-M8T module:
Passive antenna used
No backup battery
UART for communication

2.3 Footprint and paste mask
Figure 5 describes the footprint and provides recommendations for the paste mask for the LEA-M8S
and LEA-M8T modules. These are recommendations only and not specifications. Note that the
copper and solder masks have the same size and position.
To improve the wetting of the half vias, reduce the amount of solder paste under the module and
increase the volume outside of the module by defining the dimensions of the paste mask to form a T-
shape (or equivalent) extending beyond the copper mask. For the stencil thickness, see Figure 6.
